List of positive integer factors of 639 that divides 639 without a remainder.
1,3,9,71,213,639
Factors of 471
List of positive integer factors of 471 that divides 471 without a remainder.
1,3,157,471
Factors of 911
List of positive integer factors of 911 that divides 911 without a remainder.
1,911
Greatest Common Factor
We found the factors 639,471,911 . The biggest common factor number is the GCF number.
So the greatest common factor 639,471,911 is 1.
Lets's calculate LCM of 24,45,214
2 | 24, 45, 214 |
3 | 12, 45, 107 |
4, 15, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 4 x 15 x 107 = 38520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38520
Therefore, the GCF of Fractions 639/24,471/45,911/214 is 1/38520
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 24,45,214 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,45,214) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(24,45,214) x common factors =1 x 6 = 6
LCM(24,45,214) = ( 24 × 45 × 214 ) / 6
LCM(24,45,214) = 231120 / 6
LCM(24,45,214) = 38520
