So the greatest common factor 43,255,676 is 1.
Lets's calculate LCM of 745,136,638
2 | 745, 136, 638 |
745, 68, 319 |
∴ So the LCM of the given numbers is 2 x 745 x 68 x 319 = 32321080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32321080
Therefore, the GCF of Fractions 43/745,255/136,676/638 is 1/32321080
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 745,136,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(745,136,638) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(745,136,638) x common factors =1 x 2 = 2
LCM(745,136,638) = ( 745 × 136 × 638 ) / 2
LCM(745,136,638) = 64642160 / 2
LCM(745,136,638) = 32321080
