So the greatest common factor 774,688 is 86.
Lets's calculate LCM of 620,246
2 | 620, 246 |
310, 123 |
∴ So the LCM of the given numbers is 2 x 310 x 123 = 76260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 86/76260
Therefore, the GCF of Fractions 774/620,688/246 is 86/76260
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 620,246 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,246) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(620,246) x common factors =2 x 1 = 2
LCM(620,246) = ( 620 × 246 ) / 2
LCM(620,246) = 152520 / 2
LCM(620,246) = 76260
