Given numbers are 637,463,728,864
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,463,728,864 is 254820384.
Find LCM of 637,463,728,864 with Prime Factorization
| 2 | 637, 463, 728, 864 |
| 2 | 637, 463, 364, 432 |
| 2 | 637, 463, 182, 216 |
| 7 | 637, 463, 91, 108 |
| 13 | 13, 463, 91, 108 |
| 1, 463, 7, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 13 x 1 x 463 x 7 x 108 = 254820384
Therefore, the lowest common multiple of 637,463,728,864 is 254820384.
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 463 x 728 x 864 = 185509239552
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
463 : 1, 463
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,463,728,864, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
463:463
728:2x 2x 2x 7x 13
864:2x 2x 2x 2x 2x 3x 3x 3
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 7x 13 = 728
Therefore, the value for common factors is 728.
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 = 185509239552/(1x728)
LCM = 185509239552/728
LCM = 254820384
Thus, we can understand that the LCM of 637,463,728,864 is 254820384.
