Lets's calculate GCF of 82,42
2 | 82, 42 |
41, 21 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 82
:1,2,41,82
Now, list down the factors of 42
:1,2,3,6,7,14,21,42
Greatest Common Factor
We found the factors 82,42 . The biggest common factor number is the GCF number.
So the greatest common factor 82,42 is 2.
Lets's calculate LCM of 783,7225
Given numbers has no common factors except 1. So, there LCM is their product i.e 5657175
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/5657175
Therefore, the GCF of Fractions 82/783,42/7225 is 2/5657175
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 783,7225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(783,7225) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(783,7225) x common factors =1 x 1 = 1
LCM(783,7225) = ( 783 × 7225 ) / 1
LCM(783,7225) = 5657175 / 1
LCM(783,7225) = 5657175
