Lets's calculate LCM of 620,248
2 | 620, 248 |
2 | 310, 124 |
31 | 155, 62 |
5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 31 x 5 x 2 = 1240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1240
Therefore, the GCF of Fractions 748/620,975/248 is 1/1240
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 620,248 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,248) = 124
common factors(in case of two or more numbers have common factors) = 1
GCF(620,248) x common factors =124 x 1 = 124
LCM(620,248) = ( 620 × 248 ) / 124
LCM(620,248) = 153760 / 124
LCM(620,248) = 1240
