We found the factors 540,465 . The biggest common factor number is the GCF number.
So the greatest common factor 540,465 is 15.
Lets's calculate LCM of 400,704
2 | 400, 704 |
2 | 200, 352 |
2 | 100, 176 |
2 | 50, 88 |
25, 44 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 25 x 44 = 17600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/17600
Therefore, the GCF of Fractions 540/400,465/704 is 15/17600
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 400,704 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(400,704) = 16
common factors(in case of two or more numbers have common factors) = 1
GCF(400,704) x common factors =16 x 1 = 16
LCM(400,704) = ( 400 × 704 ) / 16
LCM(400,704) = 281600 / 16
LCM(400,704) = 17600
