Greatest Common Factor
We found the factors 49,62,624 . The biggest common factor number is the GCF number.
So the greatest common factor 49,62,624 is 1.
Lets's calculate LCM of 42,86,769
2 | 42, 86, 769 |
21, 43, 769 |
∴ So the LCM of the given numbers is 2 x 21 x 43 x 769 = 1388814
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1388814
Therefore, the GCF of Fractions 49/42,62/86,624/769 is 1/1388814
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 42,86,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,86,769) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(42,86,769) x common factors =1 x 2 = 2
LCM(42,86,769) = ( 42 × 86 × 769 ) / 2
LCM(42,86,769) = 2777628 / 2
LCM(42,86,769) = 1388814
