1,67,83,5561
Greatest Common Factor
We found the factors 390,5561 . The biggest common factor number is the GCF number.
So the greatest common factor 390,5561 is 1.
Lets's calculate LCM of 742,394
2 | 742, 394 |
371, 197 |
∴ So the LCM of the given numbers is 2 x 371 x 197 = 146174
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/146174
Therefore, the GCF of Fractions 390/742,5561/394 is 1/146174
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 742,394 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(742,394) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(742,394) x common factors =2 x 1 = 2
LCM(742,394) = ( 742 × 394 ) / 2
LCM(742,394) = 292348 / 2
LCM(742,394) = 146174
