1,17,71,1207
Factors of 1478
List of positive integer factors of 1478 that divides 1478 without a remainder.
1,2,739,1478
Greatest Common Factor
We found the factors 1207,1478 . The biggest common factor number is the GCF number.
So the greatest common factor 1207,1478 is 1.
Lets's calculate LCM of 917,4860
Given numbers has no common factors except 1. So, there LCM is their product i.e 4456620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4456620
Therefore, the GCF of Fractions 1207/917,1478/4860 is 1/4456620
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 917,4860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(917,4860) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(917,4860) x common factors =1 x 1 = 1
LCM(917,4860) = ( 917 × 4860 ) / 1
LCM(917,4860) = 4456620 / 1
LCM(917,4860) = 4456620
