Greatest Common Factor

We found the factors 48,57,66,71 . The biggest common factor number is the GCF number.
So the greatest common factor 48,57,66,71 is 1.

Lets's calculate LCM of 91,70,18,40

2 91, 70, 18, 40
5 91, 35, 9, 20
7 91, 7, 9, 4
13, 1, 9, 4

∴ So the LCM of the given numbers is 2 x 5 x 7 x 13 x 1 x 9 x 4 = 32760

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32760

Therefore, the GCF of Fractions 48/91,57/70,66/18,71/40 is 1/32760

Least Common Multiple of 91,70,18,40 with GCF Formula

Least Common Multiple of 91,70,18,40 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 91,70,18,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,70,18,40) = 1

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

GCF(91,70,18,40) x common factors =1 x 140 = 140

LCM(91,70,18,40) = ( 91 × 70 × 18 × 40 ) / 140

LCM(91,70,18,40) = 4586400 / 140

LCM(91,70,18,40) = 32760
