Greatest Common Factor
We found the factors 649,356,756 . The biggest common factor number is the GCF number.
So the greatest common factor 649,356,756 is 1.
Lets's calculate LCM of 79,19,646
19 | 79, 19, 646 |
79, 1, 34 |
∴ So the LCM of the given numbers is 19 x 79 x 1 x 34 = 51034
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51034
Therefore, the GCF of Fractions 649/79,356/19,756/646 is 1/51034
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 79,19,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,19,646) = 1
common factors(in case of two or more numbers have common factors) = 19
GCF(79,19,646) x common factors =1 x 19 = 19
LCM(79,19,646) = ( 79 × 19 × 646 ) / 19
LCM(79,19,646) = 969646 / 19
LCM(79,19,646) = 51034
