Lets's calculate LCM of 88,21,112

2 88, 21, 112
2 44, 21, 56
2 22, 21, 28
7 11, 21, 14
11, 3, 2

∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 11 x 3 x 2 = 3696

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3696

Therefore, the GCF of Fractions 82/88,83/21,428/112 is 1/3696

Least Common Multiple of 88,21,112 with GCF Formula

Least Common Multiple of 88,21,112 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 88,21,112 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(88,21,112) = 1

common factors(in case of two or more numbers have common factors) = 56

GCF(88,21,112) x common factors =1 x 56 = 56

LCM(88,21,112) = ( 88 × 21 × 112 ) / 56

LCM(88,21,112) = 206976 / 56

LCM(88,21,112) = 3696
