Greatest Common Factor
We found the factors 411,7471 . The biggest common factor number is the GCF number.
So the greatest common factor 411,7471 is 1.
Lets's calculate LCM of 980,7380
2 | 980, 7380 |
2 | 490, 3690 |
5 | 245, 1845 |
49, 369 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 49 x 369 = 361620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/361620
Therefore, the GCF of Fractions 411/980,7471/7380 is 1/361620
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 980,7380 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(980,7380) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(980,7380) x common factors =20 x 1 = 20
LCM(980,7380) = ( 980 × 7380 ) / 20
LCM(980,7380) = 7232400 / 20
LCM(980,7380) = 361620
