Greatest Common Factor

We found the factors 65,70,37,86 . The biggest common factor number is the GCF number.
So the greatest common factor 65,70,37,86 is 1.

Lets's calculate LCM of 77,30,31,31

31 77, 30, 31, 31
77, 30, 1, 1

∴ So the LCM of the given numbers is 31 x 77 x 30 x 1 x 1 = 71610

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/71610

Therefore, the GCF of Fractions 65/77,70/30,37/31,86/31 is 1/71610

Least Common Multiple of 77,30,31,31 with GCF Formula

Least Common Multiple of 77,30,31,31 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 77,30,31,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,30,31,31) = 1

common factors(in case of two or more numbers have common factors) = 31

GCF(77,30,31,31) x common factors =1 x 31 = 31

LCM(77,30,31,31) = ( 77 × 30 × 31 × 31 ) / 31

LCM(77,30,31,31) = 2219910 / 31

LCM(77,30,31,31) = 71610
