Greatest Common Factor

We found the factors 72,68,82,57 . The biggest common factor number is the GCF number.
So the greatest common factor 72,68,82,57 is 1.

Lets's calculate LCM of 70,93,72,35

2 70, 93, 72, 35
3 35, 93, 36, 35
5 35, 31, 12, 35
7 7, 31, 12, 7
1, 31, 12, 1

∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 31 x 12 x 1 = 78120

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/78120

Therefore, the GCF of Fractions 72/70,68/93,82/72,57/35 is 1/78120

Least Common Multiple of 70,93,72,35 with GCF Formula

Least Common Multiple of 70,93,72,35 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 70,93,72,35 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,93,72,35) = 1

common factors(in case of two or more numbers have common factors) = 210

GCF(70,93,72,35) x common factors =1 x 210 = 210

LCM(70,93,72,35) = ( 70 × 93 × 72 × 35 ) / 210

LCM(70,93,72,35) = 16405200 / 210

LCM(70,93,72,35) = 78120
