The LCM of 416,620,715,623 is 441881440.
Find LCM of 416,620,715,623 with Prime Factorization
| 2 | 416, 620, 715, 623 |
| 2 | 208, 310, 715, 623 |
| 5 | 104, 155, 715, 623 |
| 13 | 104, 31, 143, 623 |
| 8, 31, 11, 623 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 8 x 31 x 11 x 623 = 441881440
Therefore, the lowest common multiple of 416,620,715,623 is 441881440.
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.
416 x 620 x 715 x 623 = 114889174400
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
715 : 1, 5, 11, 13, 55, 65, 143, 715
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,620,715,623, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
620:2x 2x 5x 31
715:5x 11x 13
623:7x 89
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 114889174400/(1x260)
LCM = 114889174400/260
LCM = 441881440
Thus, we can understand that the LCM of 416,620,715,623 is 441881440.
