2 | 158, 138 |
79, 69 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 158
:1,2,79,158
Now, list down the factors of 138
:1,2,3,6,23,46,69,138
Greatest Common Factor
We found the factors 158,138 . The biggest common factor number is the GCF number.
So the greatest common factor 158,138 is 2.
Lets's calculate LCM of 71,679
Given numbers has no common factors except 1. So, there LCM is their product i.e 48209
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/48209
Therefore, the GCF of Fractions 158/71,138/679 is 2/48209
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 71,679 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,679) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,679) x common factors =1 x 1 = 1
LCM(71,679) = ( 71 × 679 ) / 1
LCM(71,679) = 48209 / 1
LCM(71,679) = 48209
