Given numbers are 721,387,853,530,951
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,387,853,530,951 is 39988065308310.
Find LCM of 721,387,853,530,951 with Prime Factorization
| 3 | 721, 387, 853, 530, 951 |
| 721, 129, 853, 530, 317 |
Multiply the prime numbers at the bottom and the left side.
3 x 721 x 129 x 853 x 530 x 317 = 39988065308310
Therefore, the lowest common multiple of 721,387,853,530,951 is 39988065308310.
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.
721 x 387 x 853 x 530 x 951 = 119964195924930
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.
721 : 1, 7, 103, 721
387 : 1, 3, 9, 43, 129, 387
853 : 1, 853
530 : 1, 2, 5, 10, 53, 106, 265, 530
951 : 1, 3, 317, 951
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,387,853,530,951, is 1.
Now, the common factors can be found like this.
721:7x 103
387:3x 3x 43
853:853
530:2x 5x 53
951:3x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 119964195924930/(1x3)
LCM = 119964195924930/3
LCM = 39988065308310
Thus, we can understand that the LCM of 721,387,853,530,951 is 39988065308310.
