Greatest Common Factor
We found the factors 248,391,256 . The biggest common factor number is the GCF number.
So the greatest common factor 248,391,256 is 1.
Lets's calculate LCM of 55,76,118
2 | 55, 76, 118 |
55, 38, 59 |
∴ So the LCM of the given numbers is 2 x 55 x 38 x 59 = 246620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/246620
Therefore, the GCF of Fractions 248/55,391/76,256/118 is 1/246620
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 55,76,118 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,76,118) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(55,76,118) x common factors =1 x 2 = 2
LCM(55,76,118) = ( 55 × 76 × 118 ) / 2
LCM(55,76,118) = 493240 / 2
LCM(55,76,118) = 246620
