Given numbers are 780,632,507,636,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,632,507,636,724 is 15369137160.
Find LCM of 780,632,507,636,724 with Prime Factorization
| 2 | 780, 632, 507, 636, 724 |
| 2 | 390, 316, 507, 318, 362 |
| 3 | 195, 158, 507, 159, 181 |
| 13 | 65, 158, 169, 53, 181 |
| 5, 158, 13, 53, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 5 x 158 x 13 x 53 x 181 = 15369137160
Therefore, the lowest common multiple of 780,632,507,636,724 is 15369137160.
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.
780 x 632 x 507 x 636 x 724 = 115084099054080
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
632 : 1, 2, 4, 8, 79, 158, 316, 632
507 : 1, 3, 13, 39, 169, 507
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,632,507,636,724, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
632:2x 2x 2x 79
507:3x 13x 13
636:2x 2x 3x 53
724:2x 2x 181
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 2x 2x 2x 3x 3x 13 = 7488
Therefore, the value for common factors is 7488.
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 = 115084099054080/(1x7488)
LCM = 115084099054080/7488
LCM = 15369137160
Thus, we can understand that the LCM of 780,632,507,636,724 is 15369137160.
