So the greatest common factor 22,485,851 is 1.
Lets's calculate LCM of 170,988,478
2 | 170, 988, 478 |
85, 494, 239 |
∴ So the LCM of the given numbers is 2 x 85 x 494 x 239 = 20071220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20071220
Therefore, the GCF of Fractions 22/170,485/988,851/478 is 1/20071220
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 170,988,478 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(170,988,478) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(170,988,478) x common factors =2 x 2 = 4
LCM(170,988,478) = ( 170 × 988 × 478 ) / 4
LCM(170,988,478) = 80284880 / 4
LCM(170,988,478) = 20071220
