Greatest Common Factor
We found the factors 231,7350 . The biggest common factor number is the GCF number.
So the greatest common factor 231,7350 is 21.
Lets's calculate LCM of 492,784
2 | 492, 784 |
2 | 246, 392 |
123, 196 |
∴ So the LCM of the given numbers is 2 x 2 x 123 x 196 = 96432
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/96432
Therefore, the GCF of Fractions 231/492,7350/784 is 21/96432
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 492,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(492,784) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(492,784) x common factors =4 x 1 = 4
LCM(492,784) = ( 492 × 784 ) / 4
LCM(492,784) = 385728 / 4
LCM(492,784) = 96432
