So the greatest common factor 153,258,861 is 3.
Lets's calculate LCM of 432,984,715
2 | 432, 984, 715 |
2 | 216, 492, 715 |
2 | 108, 246, 715 |
3 | 54, 123, 715 |
18, 41, 715 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 18 x 41 x 715 = 12664080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/12664080
Therefore, the GCF of Fractions 153/432,258/984,861/715 is 3/12664080
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 432,984,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(432,984,715) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(432,984,715) x common factors =1 x 24 = 24
LCM(432,984,715) = ( 432 × 984 × 715 ) / 24
LCM(432,984,715) = 303937920 / 24
LCM(432,984,715) = 12664080
