Given numbers are 631,316,884,689,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,316,884,689,817 is 1908124209316.
Find LCM of 631,316,884,689,817 with Prime Factorization
| 2 | 631, 316, 884, 689, 817 |
| 2 | 631, 158, 442, 689, 817 |
| 13 | 631, 79, 221, 689, 817 |
| 631, 79, 17, 53, 817 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 631 x 79 x 17 x 53 x 817 = 1908124209316
Therefore, the lowest common multiple of 631,316,884,689,817 is 1908124209316.
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.
631 x 316 x 884 x 689 x 817 = 99222458884432
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.
631 : 1, 631
316 : 1, 2, 4, 79, 158, 316
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
689 : 1, 13, 53, 689
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,316,884,689,817, is 1.
Now, the common factors can be found like this.
631:631
316:2x 2x 79
884:2x 2x 13x 17
689:13x 53
817:19x 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 13 = 52
Therefore, the value for common factors is 52.
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 = 99222458884432/(1x52)
LCM = 99222458884432/52
LCM = 1908124209316
Thus, we can understand that the LCM of 631,316,884,689,817 is 1908124209316.
