Given numbers are 637,125,510,490,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,125,510,490,638 is 2590838250.
Find LCM of 637,125,510,490,638 with Prime Factorization
| 2 | 637, 125, 510, 490, 638 |
| 5 | 637, 125, 255, 245, 319 |
| 7 | 637, 25, 51, 49, 319 |
| 7 | 91, 25, 51, 7, 319 |
| 13, 25, 51, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 13 x 25 x 51 x 1 x 319 = 2590838250
Therefore, the lowest common multiple of 637,125,510,490,638 is 2590838250.
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.
637 x 125 x 510 x 490 x 638 = 12695107425000
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.
637 : 1, 7, 13, 49, 91, 637
125 : 1, 5, 25, 125
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,125,510,490,638, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
125:5x 5x 5
510:2x 3x 5x 17
490:2x 5x 7x 7
638:2x 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 5x 5x 7x 7 = 4900
Therefore, the value for common factors is 4900.
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 = 12695107425000/(1x4900)
LCM = 12695107425000/4900
LCM = 2590838250
Thus, we can understand that the LCM of 637,125,510,490,638 is 2590838250.
