Find LCM of 630,561,515,187,268 with Prime Factorization
| 2 | 630, 561, 515, 187, 268 |
| 3 | 315, 561, 515, 187, 134 |
| 5 | 105, 187, 515, 187, 134 |
| 11 | 21, 187, 103, 187, 134 |
| 17 | 21, 17, 103, 17, 134 |
| 21, 1, 103, 1, 134 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 21 x 1 x 103 x 1 x 134 = 1626013620
Therefore, the lowest common multiple of 630,561,515,187,268 is 1626013620.
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.
630 x 561 x 515 x 187 x 268 = 9121936408200
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
561 : 1, 3, 11, 17, 33, 51, 187, 561
515 : 1, 5, 103, 515
187 : 1, 11, 17, 187
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,561,515,187,268, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
561:3x 11x 17
515:5x 103
187:11x 17
268:2x 2x 67
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 11x 17 = 5610
Therefore, the value for common factors is 5610.
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 = 9121936408200/(1x5610)
LCM = 9121936408200/5610
LCM = 1626013620
Thus, we can understand that the LCM of 630,561,515,187,268 is 1626013620.
