So the greatest common factor 851,825 is 1.
Lets's calculate LCM of 861,938
7 | 861, 938 |
123, 134 |
∴ So the LCM of the given numbers is 7 x 123 x 134 = 115374
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/115374
Therefore, the GCF of Fractions 851/861,825/938 is 1/115374
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 861,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(861,938) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(861,938) x common factors =7 x 1 = 7
LCM(861,938) = ( 861 × 938 ) / 7
LCM(861,938) = 807618 / 7
LCM(861,938) = 115374
