So the greatest common factor 17,305,942 is 1.
Lets's calculate LCM of 661,478,128
2 | 661, 478, 128 |
661, 239, 64 |
∴ So the LCM of the given numbers is 2 x 661 x 239 x 64 = 20221312
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20221312
Therefore, the GCF of Fractions 17/661,305/478,942/128 is 1/20221312
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 661,478,128 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(661,478,128) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(661,478,128) x common factors =1 x 2 = 2
LCM(661,478,128) = ( 661 × 478 × 128 ) / 2
LCM(661,478,128) = 40442624 / 2
LCM(661,478,128) = 20221312
