Greatest Common Factor

We found the factors 77,32,32,66,181,76,69,443,60,18 . The biggest common factor number is the GCF number.
So the greatest common factor 77,32,32,66,181,76,69,443,60,18 is 1.

Lets's calculate LCM of 8,8,1,5,2,1,8,9,3,8

2 8, 8, 1, 5, 2, 1, 8, 9, 3, 8
2 4, 4, 1, 5, 1, 1, 4, 9, 3, 4
2 2, 2, 1, 5, 1, 1, 2, 9, 3, 2
3 1, 1, 1, 5, 1, 1, 1, 9, 3, 1
1, 1, 1, 5, 1, 1, 1, 1, 3, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 1 x 1 x 1 x 5 x 1 x 1 x 1 x 1 x 3 x 1 = 360

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/360

Therefore, the GCF of Fractions 77/8,32/8,32/1,66/5,181/2,76/1,69/8,443/9,60/3,18/8 is 1/360

Least Common Multiple of 8,8,1,5,2,1,8,9,3,8 with GCF Formula

Least Common Multiple of 8,8,1,5,2,1,8,9,3,8 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 8,8,1,5,2,1,8,9,3,8 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8,8,1,5,2,1,8,9,3,8) = 1

common factors(in case of two or more numbers have common factors) = 3072

GCF(8,8,1,5,2,1,8,9,3,8) x common factors =1 x 3072 = 3072

LCM(8,8,1,5,2,1,8,9,3,8) = ( 8 × 8 × 1 × 5 × 2 × 1 × 8 × 9 × 3 × 8 ) / 3072

LCM(8,8,1,5,2,1,8,9,3,8) = 1105920 / 3072

LCM(8,8,1,5,2,1,8,9,3,8) = 360
