So the greatest common factor 97,75,748 is 1.
Lets's calculate LCM of 620,716,788
2 | 620, 716, 788 |
2 | 310, 358, 394 |
155, 179, 197 |
∴ So the LCM of the given numbers is 2 x 2 x 155 x 179 x 197 = 21863060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21863060
Therefore, the GCF of Fractions 97/620,75/716,748/788 is 1/21863060
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 620,716,788 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,716,788) = 4
common factors(in case of two or more numbers have common factors) = 4
GCF(620,716,788) x common factors =4 x 4 = 16
LCM(620,716,788) = ( 620 × 716 × 788 ) / 16
LCM(620,716,788) = 349808960 / 16
LCM(620,716,788) = 21863060
