Given numbers are 961,117,328,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,117,328,520 is 184396680.
Find LCM of 961,117,328,520 with Prime Factorization
| 2 | 961, 117, 328, 520 |
| 2 | 961, 117, 164, 260 |
| 2 | 961, 117, 82, 130 |
| 13 | 961, 117, 41, 65 |
| 961, 9, 41, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 961 x 9 x 41 x 5 = 184396680
Therefore, the lowest common multiple of 961,117,328,520 is 184396680.
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.
961 x 117 x 328 x 520 = 19177254720
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.
961 : 1, 31, 961
117 : 1, 3, 9, 13, 39, 117
328 : 1, 2, 4, 8, 41, 82, 164, 328
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,117,328,520, is 1.
Now, the common factors can be found like this.
961:31x 31
117:3x 3x 13
328:2x 2x 2x 41
520:2x 2x 2x 5x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 19177254720/(1x104)
LCM = 19177254720/104
LCM = 184396680
Thus, we can understand that the LCM of 961,117,328,520 is 184396680.
