Given numbers are 762,648,628,642,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,648,628,642,957 is 441014470776.
Find LCM of 762,648,628,642,957 with Prime Factorization
| 2 | 762, 648, 628, 642, 957 |
| 2 | 381, 324, 314, 321, 957 |
| 3 | 381, 162, 157, 321, 957 |
| 127, 54, 157, 107, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 54 x 157 x 107 x 319 = 441014470776
Therefore, the lowest common multiple of 762,648,628,642,957 is 441014470776.
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.
762 x 648 x 628 x 642 x 957 = 190518251375232
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
628 : 1, 2, 4, 157, 314, 628
642 : 1, 2, 3, 6, 107, 214, 321, 642
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,648,628,642,957, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
648:2x 2x 2x 3x 3x 3x 3
628:2x 2x 157
642:2x 3x 107
957:3x 11x 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 2x 2x 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 190518251375232/(1x432)
LCM = 190518251375232/432
LCM = 441014470776
Thus, we can understand that the LCM of 762,648,628,642,957 is 441014470776.
