Given numbers are 736,878,103,940,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 736,878,103,940,989 is 336291489760.
Find LCM of 736,878,103,940,989 with Prime Factorization
| 2 | 736, 878, 103, 940, 989 |
| 2 | 368, 439, 103, 470, 989 |
| 23 | 184, 439, 103, 235, 989 |
| 8, 439, 103, 235, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 8 x 439 x 103 x 235 x 43 = 336291489760
Therefore, the lowest common multiple of 736,878,103,940,989 is 336291489760.
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.
736 x 878 x 103 x 940 x 989 = 61877634115840
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.
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
878 : 1, 2, 439, 878
103 : 1, 103
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,878,103,940,989, is 1.
Now, the common factors can be found like this.
736:2x 2x 2x 2x 2x 23
878:2x 439
103:103
940:2x 2x 5x 47
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.
2x 2x 2x 23 = 184
Therefore, the value for common factors is 184.
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 = 61877634115840/(1x184)
LCM = 61877634115840/184
LCM = 336291489760
Thus, we can understand that the LCM of 736,878,103,940,989 is 336291489760.
