Find LCM of 316,638,165,945,403 with Prime Factorization
| 2 | 316, 638, 165, 945, 403 |
| 3 | 158, 319, 165, 945, 403 |
| 5 | 158, 319, 55, 315, 403 |
| 11 | 158, 319, 11, 63, 403 |
| 158, 29, 1, 63, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 158 x 29 x 1 x 63 x 403 = 38389691340
Therefore, the lowest common multiple of 316,638,165,945,403 is 38389691340.
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.
316 x 638 x 165 x 945 x 403 = 12668598142200
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.
316 : 1, 2, 4, 79, 158, 316
638 : 1, 2, 11, 22, 29, 58, 319, 638
165 : 1, 3, 5, 11, 15, 33, 55, 165
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 316,638,165,945,403, is 1.
Now, the common factors can be found like this.
316:2x 2x 79
638:2x 11x 29
165:3x 5x 11
945:3x 3x 3x 5x 7
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 12668598142200/(1x330)
LCM = 12668598142200/330
LCM = 38389691340
Thus, we can understand that the LCM of 316,638,165,945,403 is 38389691340.
