:1,2,4,5,8,10,16,20,25,40,50,80,100,200,400
Now, list down the factors of 4260
:1,2,3,4,5,6,10,12,15,20,30,60,71,142,213,284,355,426,710,852,1065,1420,2130,4260
Greatest Common Factor
We found the factors 400,4260 . The biggest common factor number is the GCF number.
So the greatest common factor 400,4260 is 20.
Lets's calculate LCM of 715,141
Given numbers has no common factors except 1. So, there LCM is their product i.e 100815
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/100815
Therefore, the GCF of Fractions 400/715,4260/141 is 20/100815
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 715,141 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,141) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(715,141) x common factors =1 x 1 = 1
LCM(715,141) = ( 715 × 141 ) / 1
LCM(715,141) = 100815 / 1
LCM(715,141) = 100815
