Lets's calculate GCF of 430,172
2 | 430, 172 |
43 | 215, 86 |
5, 2 |
∴ So the GCF of the given numbers is 2 x 43 = 86
Now, list down the factors of 430
:1,2,5,10,43,86,215,430
Now, list down the factors of 172
:1,2,4,43,86,172
Greatest Common Factor
We found the factors 430,172 . The biggest common factor number is the GCF number.
So the greatest common factor 430,172 is 86.
Lets's calculate LCM of 994,921
Given numbers has no common factors except 1. So, there LCM is their product i.e 915474
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 86/915474
Therefore, the GCF of Fractions 430/994,172/921 is 86/915474
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 994,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(994,921) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(994,921) x common factors =1 x 1 = 1
LCM(994,921) = ( 994 × 921 ) / 1
LCM(994,921) = 915474 / 1
LCM(994,921) = 915474
