Lets's calculate GCF of 621,156
3 | 621, 156 |
207, 52 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 621
:1,3,9,23,27,69,207,621
Now, list down the factors of 156
:1,2,3,4,6,12,13,26,39,52,78,156
Greatest Common Factor
We found the factors 621,156 . The biggest common factor number is the GCF number.
So the greatest common factor 621,156 is 3.
Lets's calculate LCM of 248,101
Given numbers has no common factors except 1. So, there LCM is their product i.e 25048
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/25048
Therefore, the GCF of Fractions 621/248,156/101 is 3/25048
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 248,101 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(248,101) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(248,101) x common factors =1 x 1 = 1
LCM(248,101) = ( 248 × 101 ) / 1
LCM(248,101) = 25048 / 1
LCM(248,101) = 25048
