So the greatest common factor 227,672 is 1.
Lets's calculate LCM of 520,438
2 | 520, 438 |
260, 219 |
∴ So the LCM of the given numbers is 2 x 260 x 219 = 113880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113880
Therefore, the GCF of Fractions 227/520,672/438 is 1/113880
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 520,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,438) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(520,438) x common factors =2 x 1 = 2
LCM(520,438) = ( 520 × 438 ) / 2
LCM(520,438) = 227760 / 2
LCM(520,438) = 113880
