So the greatest common factor 11,31,86,193 is 1.

Lets's calculate LCM of 24,90,60,20

2 24, 90, 60, 20
2 12, 45, 30, 10
3 6, 45, 15, 5
5 2, 5, 15, 5
2, 1, 3, 1

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

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

Therefore, the GCF of Fractions 11/24,31/90,86/60,193/20 is 1/360

Least Common Multiple of 24,90,60,20 with GCF Formula

Least Common Multiple of 24,90,60,20 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 24,90,60,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(24,90,60,20) = 2

common factors(in case of two or more numbers have common factors) = 3600

GCF(24,90,60,20) x common factors =2 x 3600 = 7200

LCM(24,90,60,20) = ( 24 × 90 × 60 × 20 ) / 7200

LCM(24,90,60,20) = 2592000 / 7200

LCM(24,90,60,20) = 360
