So the greatest common factor 74,772,835 is 1.
Lets's calculate LCM of 90,30,793
2 | 90, 30, 793 |
3 | 45, 15, 793 |
5 | 5, 15, 793 |
1, 3, 793 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 3 x 793 = 71370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/71370
Therefore, the GCF of Fractions 74/90,772/30,835/793 is 1/71370
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 90,30,793 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,30,793) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(90,30,793) x common factors =1 x 30 = 30
LCM(90,30,793) = ( 90 × 30 × 793 ) / 30
LCM(90,30,793) = 2141100 / 30
LCM(90,30,793) = 71370
