Greatest Common Factor
We found the factors 42,248,550 . The biggest common factor number is the GCF number.
So the greatest common factor 42,248,550 is 2.
Lets's calculate LCM of 17,22,342
2 | 17, 22, 342 |
17, 11, 171 |
∴ So the LCM of the given numbers is 2 x 17 x 11 x 171 = 63954
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/63954
Therefore, the GCF of Fractions 42/17,248/22,550/342 is 2/63954
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 17,22,342 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,22,342) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(17,22,342) x common factors =1 x 2 = 2
LCM(17,22,342) = ( 17 × 22 × 342 ) / 2
LCM(17,22,342) = 127908 / 2
LCM(17,22,342) = 63954
