Given numbers are 744,663,837,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 744,663,837,989 is 1463538024.
Find LCM of 744,663,837,989 with Prime Factorization
| 3 | 744, 663, 837, 989 |
| 31 | 248, 221, 279, 989 |
| 8, 221, 9, 989 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 8 x 221 x 9 x 989 = 1463538024
Therefore, the lowest common multiple of 744,663,837,989 is 1463538024.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
744 x 663 x 837 x 989 = 408327108696
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
663 : 1, 3, 13, 17, 39, 51, 221, 663
837 : 1, 3, 9, 27, 31, 93, 279, 837
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 744,663,837,989, is 1.
Now, the common factors can be found like this.
744:2x 2x 2x 3x 31
663:3x 13x 17
837:3x 3x 3x 31
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 31 = 279
Therefore, the value for common factors is 279.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 408327108696/(1x279)
LCM = 408327108696/279
LCM = 1463538024
Thus, we can understand that the LCM of 744,663,837,989 is 1463538024.
