List of positive integer factors of 78 that divides 78 without a remainder.
1,2,3,6,13,26,39,78
Factors of 634
List of positive integer factors of 634 that divides 634 without a remainder.
1,2,317,634
Greatest Common Factor
We found the factors 31,78,634 . The biggest common factor number is the GCF number.
So the greatest common factor 31,78,634 is 1.
Lets's calculate LCM of 917,843,320
Given numbers has no common factors except 1. So, there LCM is their product i.e 247369920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/247369920
Therefore, the GCF of Fractions 31/917,78/843,634/320 is 1/247369920
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 917,843,320 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(917,843,320) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(917,843,320) x common factors =1 x 1 = 1
LCM(917,843,320) = ( 917 × 843 × 320 ) / 1
LCM(917,843,320) = 247369920 / 1
LCM(917,843,320) = 247369920
