Given numbers are 637,728,335,626,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,728,335,626,390 is 1603023240.
Find LCM of 637,728,335,626,390 with Prime Factorization
| 2 | 637, 728, 335, 626, 390 |
| 5 | 637, 364, 335, 313, 195 |
| 7 | 637, 364, 67, 313, 39 |
| 13 | 91, 52, 67, 313, 39 |
| 7, 4, 67, 313, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 7 x 4 x 67 x 313 x 3 = 1603023240
Therefore, the lowest common multiple of 637,728,335,626,390 is 1603023240.
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 728 x 335 x 626 x 390 = 37927529858400
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
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
335 : 1, 5, 67, 335
626 : 1, 2, 313, 626
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,728,335,626,390, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
728:2x 2x 2x 7x 13
335:5x 67
626:2x 313
390:2x 3x 5x 13
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 7x 13x 13 = 23660
Therefore, the value for common factors is 23660.
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 = 37927529858400/(1x23660)
LCM = 37927529858400/23660
LCM = 1603023240
Thus, we can understand that the LCM of 637,728,335,626,390 is 1603023240.
