So the greatest common factor 32,128,796 is 4.
Lets's calculate LCM of 45,78,636
2 | 45, 78, 636 |
3 | 45, 39, 318 |
15, 13, 106 |
∴ So the LCM of the given numbers is 2 x 3 x 15 x 13 x 106 = 124020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/124020
Therefore, the GCF of Fractions 32/45,128/78,796/636 is 4/124020
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 45,78,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,78,636) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(45,78,636) x common factors =3 x 6 = 18
LCM(45,78,636) = ( 45 × 78 × 636 ) / 18
LCM(45,78,636) = 2232360 / 18
LCM(45,78,636) = 124020
