:1,2,4,107,214,428
Now, list down the factors of 521
:1,521
Greatest Common Factor
We found the factors 428,521 . The biggest common factor number is the GCF number.
So the greatest common factor 428,521 is 1.
Lets's calculate LCM of 422,225
Given numbers has no common factors except 1. So, there LCM is their product i.e 94950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/94950
Therefore, the GCF of Fractions 428/422,521/225 is 1/94950
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 422,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(422,225) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(422,225) x common factors =1 x 1 = 1
LCM(422,225) = ( 422 × 225 ) / 1
LCM(422,225) = 94950 / 1
LCM(422,225) = 94950
