Greatest Common Factor
We found the factors 159,172 . The biggest common factor number is the GCF number.
So the greatest common factor 159,172 is 1.
Lets's calculate LCM of 38,636
2 | 38, 636 |
19, 318 |
∴ So the LCM of the given numbers is 2 x 19 x 318 = 12084
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12084
Therefore, the GCF of Fractions 159/38,172/636 is 1/12084
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 38,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,636) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(38,636) x common factors =2 x 1 = 2
LCM(38,636) = ( 38 × 636 ) / 2
LCM(38,636) = 24168 / 2
LCM(38,636) = 12084
