positive proper fractions: 277/420, 276/427, 295/438, 294/419
Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
- To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
The fraction: 277/420
277/420 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 277 is a prime number.
- 420 = 22 × 3 × 5 × 7
- GCF (277; 420) = 1
The fraction: 276/427
276/427 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 276 = 22 × 3 × 23
- 427 = 7 × 61
- GCF (276; 427) = 1
The fraction: 295/438
295/438 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 295 = 5 × 59
- 438 = 2 × 3 × 73
- GCF (295; 438) = 1
The fraction: 294/419
294/419 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 294 = 2 × 3 × 72
- 419 is a prime number.
- GCF (294; 419) = 1
Calculate the common denominator
The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
To calculate the LCM, we need the prime factorization of the denominators:
420 = 22 × 3 × 5 × 7
427 = 7 × 61
438 = 2 × 3 × 73
419 is a prime number.
Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).
LCM (420, 427, 438, 419) = 22 × 3 × 5 × 7 × 61 × 73 × 419 = 783,638,940
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
277/420 ⟶ 783,638,940 ÷ 420 = (22 × 3 × 5 × 7 × 61 × 73 × 419) ÷ (22 × 3 × 5 × 7) = 1,865,807
276/427 ⟶ 783,638,940 ÷ 427 = (22 × 3 × 5 × 7 × 61 × 73 × 419) ÷ (7 × 61) = 1,835,220
295/438 ⟶ 783,638,940 ÷ 438 = (22 × 3 × 5 × 7 × 61 × 73 × 419) ÷ (2 × 3 × 73) = 1,789,130
294/419 ⟶ 783,638,940 ÷ 419 = (22 × 3 × 5 × 7 × 61 × 73 × 419) ÷ 419 = 1,870,260
Make the denominators of the fractions the same:
- Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
- This way all the fractions will have the same denominator:
277/420 = (1,865,807 × 277)/(1,865,807 × 420) = 516,828,539/783,638,940
276/427 = (1,835,220 × 276)/(1,835,220 × 427) = 506,520,720/783,638,940
295/438 = (1,789,130 × 295)/(1,789,130 × 438) = 527,793,350/783,638,940
294/419 = (1,870,260 × 294)/(1,870,260 × 419) = 549,856,440/783,638,940
