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: 1,047/52
1,047/52 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 1,047 = 3 × 349
- 52 = 22 × 13
- GCF (1,047; 52) = 1
The fraction: 1,052/70
- The prime factorizations of the numerator and denominator:
- 1,052 = 22 × 263
- 70 = 2 × 5 × 7
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (1,052; 70) = 2
1,052/70 = (1,052 ÷ 2)/(70 ÷ 2) = 526/35
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
1,052/70 = (22 × 263)/(2 × 5 × 7) = ((22 × 263) ÷ 2)/((2 × 5 × 7) ÷ 2) = 526/35

572/72 = (572 ÷ 4)/(72 ÷ 4) = 143/18
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
572/72 = (22 × 11 × 13)/(23 × 32) = ((22 × 11 × 13) ÷ 22)/((23 × 32) ÷ 22) = 143/18

The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
150/70 = (2 × 3 × 52)/(2 × 5 × 7) = ((2 × 3 × 52) ÷ (2 × 5))/((2 × 5 × 7) ÷ (2 × 5)) = 15/7
The fraction: 112/68
- 112 = 24 × 7
