1,2,4,8
Factors of 987
List of positive integer factors of 987 that divides 987 without a remainder.
1,3,7,21,47,141,329,987
Factors of 890
List of positive integer factors of 890 that divides 890 without a remainder.
1,2,5,10,89,178,445,890
Greatest Common Factor
We found the factors 8,987,890 . The biggest common factor number is the GCF number.
So the greatest common factor 8,987,890 is 1.
Lets's calculate LCM of 14,40,72
2 | 14, 40, 72 |
2 | 7, 20, 36 |
2 | 7, 10, 18 |
7, 5, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 5 x 9 = 2520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2520
Therefore, the GCF of Fractions 8/14,987/40,890/72 is 1/2520
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 14,40,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,40,72) = 2
common factors(in case of two or more numbers have common factors) = 8
GCF(14,40,72) x common factors =2 x 8 = 16
LCM(14,40,72) = ( 14 × 40 × 72 ) / 16
LCM(14,40,72) = 40320 / 16
LCM(14,40,72) = 2520
