Lets's calculate GCF of 730,408
2 | 730, 408 |
365, 204 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 730
:1,2,5,10,73,146,365,730
Now, list down the factors of 408
:1,2,3,4,6,8,12,17,24,34,51,68,102,136,204,408
Greatest Common Factor
We found the factors 730,408 . The biggest common factor number is the GCF number.
So the greatest common factor 730,408 is 2.
Lets's calculate LCM of 77,531
Given numbers has no common factors except 1. So, there LCM is their product i.e 40887
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/40887
Therefore, the GCF of Fractions 730/77,408/531 is 2/40887
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 77,531 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,531) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,531) x common factors =1 x 1 = 1
LCM(77,531) = ( 77 × 531 ) / 1
LCM(77,531) = 40887 / 1
LCM(77,531) = 40887
