Given numbers are 658,979,638,875,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,979,638,875,721 is 240521454250.
Find LCM of 658,979,638,875,721 with Prime Factorization
| 2 | 658, 979, 638, 875, 721 |
| 7 | 329, 979, 319, 875, 721 |
| 11 | 47, 979, 319, 125, 103 |
| 47, 89, 29, 125, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 47 x 89 x 29 x 125 x 103 = 240521454250
Therefore, the lowest common multiple of 658,979,638,875,721 is 240521454250.
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.
658 x 979 x 638 x 875 x 721 = 259282127681500
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
979 : 1, 11, 89, 979
638 : 1, 2, 11, 22, 29, 58, 319, 638
875 : 1, 5, 7, 25, 35, 125, 175, 875
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,979,638,875,721, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
979:11x 89
638:2x 11x 29
875:5x 5x 5x 7
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 11 = 1078
Therefore, the value for common factors is 1078.
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 = 259282127681500/(1x1078)
LCM = 259282127681500/1078
LCM = 240521454250
Thus, we can understand that the LCM of 658,979,638,875,721 is 240521454250.
