To find the highest common factor of 623,644, we have to find the factors of both numbers and list the highest common factor.
The factors of 623 are 1, 7, 89, 623
The factors of 644 are 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
The HCF of 623,644 is 7.
Lets's calculate GCF of 623,644
7 | 623, 644 |
89, 92 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 623
:1,7,89,623
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 623,644 . The biggest common factor number is the GCF number.
So the greatest common factor 623,644 is 7.
Lets's calculate LCM of 71,123
Given numbers has no common factors except 1. So, there LCM is their product i.e 8733
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/8733
Therefore, the GCF of Fractions 623/71,644/123 is 7/8733
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 71,123 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,123) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,123) x common factors =1 x 1 = 1
LCM(71,123) = ( 71 × 123 ) / 1
LCM(71,123) = 8733 / 1
LCM(71,123) = 8733
