Lets's calculate LCM of 236,876
2 | 236, 876 |
2 | 118, 438 |
59, 219 |
∴ So the LCM of the given numbers is 2 x 2 x 59 x 219 = 51684
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/51684
Therefore, the GCF of Fractions 581/236,280/876 is 7/51684
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 236,876 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(236,876) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(236,876) x common factors =4 x 1 = 4
LCM(236,876) = ( 236 × 876 ) / 4
LCM(236,876) = 206736 / 4
LCM(236,876) = 51684
