Lets's calculate LCM of 35,20,28

2 35, 20, 28
2 35, 10, 14
5 35, 5, 7
7 7, 1, 7
1, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 1 x 1 = 140

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/140

Therefore, the GCF of Fractions 5/35,866/20,856/28 is 1/140

Least Common Multiple of 35,20,28 with GCF Formula

Least Common Multiple of 35,20,28 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 35,20,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(35,20,28) = 1

common factors(in case of two or more numbers have common factors) = 140

GCF(35,20,28) x common factors =1 x 140 = 140

LCM(35,20,28) = ( 35 × 20 × 28 ) / 140

LCM(35,20,28) = 19600 / 140

LCM(35,20,28) = 140
