Lets's calculate LCM of 690,850,856

2 690, 850, 856
5 345, 425, 428
69, 85, 428

∴ So the LCM of the given numbers is 2 x 5 x 69 x 85 x 428 = 25102200

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25102200

Therefore, the GCF of Fractions 80/690,85/850,621/856 is 1/25102200

Least Common Multiple of 690,850,856 with GCF Formula

Least Common Multiple of 690,850,856 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 690,850,856 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,850,856) = 2

common factors(in case of two or more numbers have common factors) = 10

GCF(690,850,856) x common factors =2 x 10 = 20

LCM(690,850,856) = ( 690 × 850 × 856 ) / 20

LCM(690,850,856) = 502044000 / 20

LCM(690,850,856) = 25102200
