Lets's calculate GCF of 668,122
2 | 668, 122 |
334, 61 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 668
:1,2,4,167,334,668
Now, list down the factors of 122
:1,2,61,122
Greatest Common Factor
We found the factors 668,122 . The biggest common factor number is the GCF number.
So the greatest common factor 668,122 is 2.
Lets's calculate LCM of 985,272
Given numbers has no common factors except 1. So, there LCM is their product i.e 267920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/267920
Therefore, the GCF of Fractions 668/985,122/272 is 2/267920
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 985,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(985,272) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(985,272) x common factors =1 x 1 = 1
LCM(985,272) = ( 985 × 272 ) / 1
LCM(985,272) = 267920 / 1
LCM(985,272) = 267920
