Now, list down the factors of 411
:1,3,137,411
Now, list down the factors of 469
:1,7,67,469
Greatest Common Factor
We found the factors 411,469 . The biggest common factor number is the GCF number.
So the greatest common factor 411,469 is 1.
Lets's calculate LCM of 640,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 77440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/77440
Therefore, the GCF of Fractions 411/640,469/121 is 1/77440
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 640,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(640,121) x common factors =1 x 1 = 1
LCM(640,121) = ( 640 × 121 ) / 1
LCM(640,121) = 77440 / 1
LCM(640,121) = 77440
