So the greatest common factor 290,609,550 is 1.
Lets's calculate LCM of 90,70,31
2 | 90, 70, 31 |
5 | 45, 35, 31 |
9, 7, 31 |
∴ So the LCM of the given numbers is 2 x 5 x 9 x 7 x 31 = 19530
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19530
Therefore, the GCF of Fractions 290/90,609/70,550/31 is 1/19530
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 90,70,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,70,31) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(90,70,31) x common factors =1 x 10 = 10
LCM(90,70,31) = ( 90 × 70 × 31 ) / 10
LCM(90,70,31) = 195300 / 10
LCM(90,70,31) = 19530
