Lets's calculate LCM of 44,20,401

2 44, 20, 401
2 22, 10, 401
11, 5, 401

∴ So the LCM of the given numbers is 2 x 2 x 11 x 5 x 401 = 88220

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/88220

Therefore, the GCF of Fractions 690/44,580/20,717/401 is 1/88220

Least Common Multiple of 44,20,401 with GCF Formula

Least Common Multiple of 44,20,401 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 44,20,401 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(44,20,401) = 1

common factors(in case of two or more numbers have common factors) = 4

GCF(44,20,401) x common factors =1 x 4 = 4

LCM(44,20,401) = ( 44 × 20 × 401 ) / 4

LCM(44,20,401) = 352880 / 4

LCM(44,20,401) = 88220
