The factors of 644 are 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
The HCF of 123,644 is 1.
Lets's calculate GCF of 123,644
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 123
:1,3,41,123
Now, list down the factors of 644
:1,2,4,7,14,23,28,46,92,161,322,644
Greatest Common Factor
We found the factors 123,644 . The biggest common factor number is the GCF number.
So the greatest common factor 123,644 is 1.
Lets's calculate LCM of 49,783
Given numbers has no common factors except 1. So, there LCM is their product i.e 38367
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38367
Therefore, the GCF of Fractions 123/49,644/783 is 1/38367
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 49,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,783) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,783) x common factors =1 x 1 = 1
LCM(49,783) = ( 49 × 783 ) / 1
LCM(49,783) = 38367 / 1
LCM(49,783) = 38367
