∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 82
:1,2,41,82
Now, list down the factors of 63
:1,3,7,9,21,63
Now, list down the factors of 37
:1,37
Greatest Common Factor
We found the factors 82,63,37 . The biggest common factor number is the GCF number.
So the greatest common factor 82,63,37 is 1.
Lets's calculate LCM of 89,72,647
Given numbers has no common factors except 1. So, there LCM is their product i.e 4145976
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4145976
Therefore, the GCF of Fractions 82/89,63/72,37/647 is 1/4145976
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 89,72,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,72,647) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,72,647) x common factors =1 x 1 = 1
LCM(89,72,647) = ( 89 × 72 × 647 ) / 1
LCM(89,72,647) = 4145976 / 1
LCM(89,72,647) = 4145976
