1,3,271,813
Factors of 973
List of positive integer factors of 973 that divides 973 without a remainder.
1,7,139,973
Greatest Common Factor
We found the factors 71,813,973 . The biggest common factor number is the GCF number.
So the greatest common factor 71,813,973 is 1.
Lets's calculate LCM of 28,43,839
Given numbers has no common factors except 1. So, there LCM is their product i.e 1010156
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1010156
Therefore, the GCF of Fractions 71/28,813/43,973/839 is 1/1010156
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 28,43,839 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,43,839) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,43,839) x common factors =1 x 1 = 1
LCM(28,43,839) = ( 28 × 43 × 839 ) / 1
LCM(28,43,839) = 1010156 / 1
LCM(28,43,839) = 1010156
