Given numbers are 168,393,636,638,795
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,393,636,638,795 is 1860446280.
Find LCM of 168,393,636,638,795 with Prime Factorization
| 2 | 168, 393, 636, 638, 795 |
| 2 | 84, 393, 318, 319, 795 |
| 3 | 42, 393, 159, 319, 795 |
| 53 | 14, 131, 53, 319, 265 |
| 14, 131, 1, 319, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 14 x 131 x 1 x 319 x 5 = 1860446280
Therefore, the lowest common multiple of 168,393,636,638,795 is 1860446280.
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.
168 x 393 x 636 x 638 x 795 = 21298389013440
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
393 : 1, 3, 131, 393
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
638 : 1, 2, 11, 22, 29, 58, 319, 638
795 : 1, 3, 5, 15, 53, 159, 265, 795
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,393,636,638,795, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
393:3x 131
636:2x 2x 3x 53
638:2x 11x 29
795:3x 5x 53
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 3x 3x 3x 53 = 11448
Therefore, the value for common factors is 11448.
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 = 21298389013440/(1x11448)
LCM = 21298389013440/11448
LCM = 1860446280
Thus, we can understand that the LCM of 168,393,636,638,795 is 1860446280.
