Greatest Common Factor
We found the factors 75,86,42,53 . The biggest common factor number is the GCF number.
So the greatest common factor 75,86,42,53 is 1.
Lets's calculate LCM of 94,76,24,361
2 | 94, 76, 24, 361 |
2 | 47, 38, 12, 361 |
19 | 47, 19, 6, 361 |
47, 1, 6, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 19 x 47 x 1 x 6 x 19 = 407208
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/407208
Therefore, the GCF of Fractions 75/94,86/76,42/24,53/361 is 1/407208
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 94,76,24,361 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,76,24,361) = 1
common factors(in case of two or more numbers have common factors) = 152
GCF(94,76,24,361) x common factors =1 x 152 = 152
LCM(94,76,24,361) = ( 94 × 76 × 24 × 361 ) / 152
LCM(94,76,24,361) = 61895616 / 152
LCM(94,76,24,361) = 407208
