We found the factors 91,20,29,94 . The biggest common factor number is the GCF number.
So the greatest common factor 91,20,29,94 is 1.

Lets's calculate LCM of 35,77,86,28

2 35, 77, 86, 28
7 35, 77, 43, 14
5, 11, 43, 2

∴ So the LCM of the given numbers is 2 x 7 x 5 x 11 x 43 x 2 = 66220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/66220

Therefore, the GCF of Fractions 91/35,20/77,29/86,94/28 is 1/66220

Least Common Multiple of 35,77,86,28 with GCF Formula

Least Common Multiple of 35,77,86,28 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 35,77,86,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(35,77,86,28) = 1

common factors(in case of two or more numbers have common factors) = 98

GCF(35,77,86,28) x common factors =1 x 98 = 98

LCM(35,77,86,28) = ( 35 × 77 × 86 × 28 ) / 98

LCM(35,77,86,28) = 6489560 / 98

LCM(35,77,86,28) = 66220
