Greatest Common Factor
We found the factors 7711,5389 . The biggest common factor number is the GCF number.
So the greatest common factor 7711,5389 is 1.
Lets's calculate LCM of 450,438
2 | 450, 438 |
3 | 225, 219 |
75, 73 |
∴ So the LCM of the given numbers is 2 x 3 x 75 x 73 = 32850
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32850
Therefore, the GCF of Fractions 7711/450,5389/438 is 1/32850
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 450,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(450,438) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(450,438) x common factors =6 x 1 = 6
LCM(450,438) = ( 450 × 438 ) / 6
LCM(450,438) = 197100 / 6
LCM(450,438) = 32850
