The LCM of 630,160,561,533,405 is 9042153120.
Find LCM of 630,160,561,533,405 with Prime Factorization
| 2 | 630, 160, 561, 533, 405 |
| 3 | 315, 80, 561, 533, 405 |
| 3 | 105, 80, 187, 533, 135 |
| 5 | 35, 80, 187, 533, 45 |
| 7, 16, 187, 533, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 16 x 187 x 533 x 9 = 9042153120
Therefore, the lowest common multiple of 630,160,561,533,405 is 9042153120.
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 160 x 561 x 533 x 405 = 12206906712000
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
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
561 : 1, 3, 11, 17, 33, 51, 187, 561
533 : 1, 13, 41, 533
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,160,561,533,405, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
160:2x 2x 2x 2x 2x 5
561:3x 11x 17
533:13x 41
405:3x 3x 3x 3x 5
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 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 12206906712000/(1x1350)
LCM = 12206906712000/1350
LCM = 9042153120
Thus, we can understand that the LCM of 630,160,561,533,405 is 9042153120.
