So the greatest common factor 20,885,523 is 1.
Lets's calculate LCM of 651,136,221
17 | 651, 136, 221 |
651, 8, 13 |
∴ So the LCM of the given numbers is 17 x 651 x 8 x 13 = 1150968
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1150968
Therefore, the GCF of Fractions 20/651,885/136,523/221 is 1/1150968
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 651,136,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(651,136,221) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(651,136,221) x common factors =1 x 17 = 17
LCM(651,136,221) = ( 651 × 136 × 221 ) / 17
LCM(651,136,221) = 19566456 / 17
LCM(651,136,221) = 1150968
