Lets's calculate LCM of 12,18,75,80

Least Common Multiple (LCM) of 12,18,75,80 By Common Division

2 12, 18, 75, 80
2 6, 9, 75, 40
3 3, 9, 75, 20
5 1, 3, 25, 20
1, 3, 5, 4

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 3 x 5 x 4 = 3600

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3600

Therefore, the GCF of Fractions 7/12,10/18,13/75,17/80 is 1/3600

Least Common Multiple of 12,18,75,80 with GCF Formula

Least Common Multiple of 12,18,75,80 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 12,18,75,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(12,18,75,80) = 1

common factors(in case of two or more numbers have common factors) = 360

GCF(12,18,75,80) x common factors =1 x 360 = 360

LCM(12,18,75,80) = ( 12 × 18 × 75 × 80 ) / 360

LCM(12,18,75,80) = 1296000 / 360

LCM(12,18,75,80) = 3600
