Greatest Common Factor
We found the factors 15,22,528 . The biggest common factor number is the GCF number.
So the greatest common factor 15,22,528 is 1.
Lets's calculate LCM of 745,393,665
5 | 745, 393, 665 |
149, 393, 133 |
∴ So the LCM of the given numbers is 5 x 149 x 393 x 133 = 38940405
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38940405
Therefore, the GCF of Fractions 15/745,22/393,528/665 is 1/38940405
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 745,393,665 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(745,393,665) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(745,393,665) x common factors =1 x 5 = 5
LCM(745,393,665) = ( 745 × 393 × 665 ) / 5
LCM(745,393,665) = 194702025 / 5
LCM(745,393,665) = 38940405
