So the greatest common factor 70,640,615 is 5.
Lets's calculate LCM of 921,555,430
3 | 921, 555, 430 |
5 | 307, 185, 430 |
307, 37, 86 |
∴ So the LCM of the given numbers is 3 x 5 x 307 x 37 x 86 = 14653110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/14653110
Therefore, the GCF of Fractions 70/921,640/555,615/430 is 5/14653110
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 921,555,430 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,555,430) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(921,555,430) x common factors =1 x 15 = 15
LCM(921,555,430) = ( 921 × 555 × 430 ) / 15
LCM(921,555,430) = 219796650 / 15
LCM(921,555,430) = 14653110
