Find LCM of 156,598,391,435 with Prime Factorization
| 2 | 156, 598, 391, 435 |
| 3 | 78, 299, 391, 435 |
| 13 | 26, 299, 391, 145 |
| 23 | 2, 23, 391, 145 |
| 2, 1, 17, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 2 x 1 x 17 x 145 = 8844420
Therefore, the lowest common multiple of 156,598,391,435 is 8844420.
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.
156 x 598 x 391 x 435 = 15866889480
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
598 : 1, 2, 13, 23, 26, 46, 299, 598
391 : 1, 17, 23, 391
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,598,391,435, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
598:2x 13x 23
391:17x 23
435:3x 5x 29
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 13x 23 = 1794
Therefore, the value for common factors is 1794.
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 = 15866889480/(1x1794)
LCM = 15866889480/1794
LCM = 8844420
Thus, we can understand that the LCM of 156,598,391,435 is 8844420.
