Given numbers are 628,817,676,786,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,817,676,786,404 is 3441773837892.
Find LCM of 628,817,676,786,404 with Prime Factorization
| 2 | 628, 817, 676, 786, 404 |
| 2 | 314, 817, 338, 393, 202 |
| 157, 817, 169, 393, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 817 x 169 x 393 x 101 = 3441773837892
Therefore, the lowest common multiple of 628,817,676,786,404 is 3441773837892.
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.
628 x 817 x 676 x 786 x 404 = 110136762812544
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.
628 : 1, 2, 4, 157, 314, 628
817 : 1, 19, 43, 817
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
786 : 1, 2, 3, 6, 131, 262, 393, 786
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,817,676,786,404, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
817:19x 43
676:2x 2x 13x 13
786:2x 3x 131
404:2x 2x 101
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 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 110136762812544/(1x32)
LCM = 110136762812544/32
LCM = 3441773837892
Thus, we can understand that the LCM of 628,817,676,786,404 is 3441773837892.
