1,3,17,51
Factors of 100
List of positive integer factors of 100 that divides 100 without a remainder.
1,2,4,5,10,20,25,50,100
Greatest Common Factor
We found the factors 28,51,100 . The biggest common factor number is the GCF number.
So the greatest common factor 28,51,100 is 1.
Lets's calculate LCM of 83,684,911
Given numbers has no common factors except 1. So, there LCM is their product i.e 51719292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51719292
Therefore, the GCF of Fractions 28/83,51/684,100/911 is 1/51719292
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 83,684,911 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,684,911) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,684,911) x common factors =1 x 1 = 1
LCM(83,684,911) = ( 83 × 684 × 911 ) / 1
LCM(83,684,911) = 51719292 / 1
LCM(83,684,911) = 51719292
