Lets's calculate LCM of 749,665
7 | 749, 665 |
107, 95 |
∴ So the LCM of the given numbers is 7 x 107 x 95 = 71155
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/71155
Therefore, the GCF of Fractions 825/749,159/665 is 3/71155
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 749,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,665) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(749,665) x common factors =7 x 1 = 7
LCM(749,665) = ( 749 × 665 ) / 7
LCM(749,665) = 498085 / 7
LCM(749,665) = 71155
