Given numbers are 631,951,221,928,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,951,221,928,684 is 7014956491296.
Find LCM of 631,951,221,928,684 with Prime Factorization
| 2 | 631, 951, 221, 928, 684 |
| 2 | 631, 951, 221, 464, 342 |
| 3 | 631, 951, 221, 232, 171 |
| 631, 317, 221, 232, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 631 x 317 x 221 x 232 x 57 = 7014956491296
Therefore, the lowest common multiple of 631,951,221,928,684 is 7014956491296.
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 951 x 221 x 928 x 684 = 84179477895552
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
951 : 1, 3, 317, 951
221 : 1, 13, 17, 221
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,951,221,928,684, is 1.
Now, the common factors can be found like this.
631:631
951:3x 317
221:13x 17
928:2x 2x 2x 2x 2x 29
684:2x 2x 3x 3x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 84179477895552/(1x12)
LCM = 84179477895552/12
LCM = 7014956491296
Thus, we can understand that the LCM of 631,951,221,928,684 is 7014956491296.
