Lets's calculate LCM of 436,216
2 | 436, 216 |
2 | 218, 108 |
109, 54 |
∴ So the LCM of the given numbers is 2 x 2 x 109 x 54 = 23544
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23544
Therefore, the GCF of Fractions 320/436,257/216 is 1/23544
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 436,216 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(436,216) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(436,216) x common factors =4 x 1 = 4
LCM(436,216) = ( 436 × 216 ) / 4
LCM(436,216) = 94176 / 4
LCM(436,216) = 23544
