So the greatest common factor 690,828,704 is 2.
Lets's calculate LCM of 621,744,654
2 | 621, 744, 654 |
3 | 621, 372, 327 |
207, 124, 109 |
∴ So the LCM of the given numbers is 2 x 3 x 207 x 124 x 109 = 16786872
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/16786872
Therefore, the GCF of Fractions 690/621,828/744,704/654 is 2/16786872
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 621,744,654 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(621,744,654) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(621,744,654) x common factors =3 x 6 = 18
LCM(621,744,654) = ( 621 × 744 × 654 ) / 18
LCM(621,744,654) = 302163696 / 18
LCM(621,744,654) = 16786872
