List of positive integer factors of 142 that divides 142 without a remainder.
1,2,71,142
Greatest Common Factor
We found the factors 56,20,142 . The biggest common factor number is the GCF number.
So the greatest common factor 56,20,142 is 2.
Lets's calculate LCM of 749,559,918
Given numbers has no common factors except 1. So, there LCM is their product i.e 384358338
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/384358338
Therefore, the GCF of Fractions 56/749,20/559,142/918 is 2/384358338
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 749,559,918 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,559,918) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(749,559,918) x common factors =1 x 1 = 1
LCM(749,559,918) = ( 749 × 559 × 918 ) / 1
LCM(749,559,918) = 384358338 / 1
LCM(749,559,918) = 384358338
Here are some samples of GCF of Fractions calculations.
