∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 81
:1,3,9,27,81
Now, list down the factors of 763
:1,7,109,763
Now, list down the factors of 739
:1,739
Greatest Common Factor
We found the factors 81,763,739 . The biggest common factor number is the GCF number.
So the greatest common factor 81,763,739 is 1.
Lets's calculate LCM of 72,43,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 2046456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2046456
Therefore, the GCF of Fractions 81/72,763/43,739/661 is 1/2046456
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 72,43,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,43,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(72,43,661) x common factors =1 x 1 = 1
LCM(72,43,661) = ( 72 × 43 × 661 ) / 1
LCM(72,43,661) = 2046456 / 1
LCM(72,43,661) = 2046456
