Greatest Common Factor

We found the factors 88,87,30,61 . The biggest common factor number is the GCF number.
So the greatest common factor 88,87,30,61 is 1.

Lets's calculate LCM of 87,12,13,130

2 87, 12, 13, 130
3 87, 6, 13, 65
13 29, 2, 13, 65
29, 2, 1, 5

∴ So the LCM of the given numbers is 2 x 3 x 13 x 29 x 2 x 1 x 5 = 22620

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22620

Therefore, the GCF of Fractions 88/87,87/12,30/13,61/130 is 1/22620

Least Common Multiple of 87,12,13,130 with GCF Formula

Least Common Multiple of 87,12,13,130 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 87,12,13,130 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,12,13,130) = 1

common factors(in case of two or more numbers have common factors) = 78

GCF(87,12,13,130) x common factors =1 x 78 = 78

LCM(87,12,13,130) = ( 87 × 12 × 13 × 130 ) / 78

LCM(87,12,13,130) = 1764360 / 78

LCM(87,12,13,130) = 22620
