Given numbers are 636,817,721,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,817,721,591 is 73804129644.
Find LCM of 636,817,721,591 with Prime Factorization
| 3 | 636, 817, 721, 591 |
| 212, 817, 721, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 212 x 817 x 721 x 197 = 73804129644
Therefore, the lowest common multiple of 636,817,721,591 is 73804129644.
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.
636 x 817 x 721 x 591 = 221412388932
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
817 : 1, 19, 43, 817
721 : 1, 7, 103, 721
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,817,721,591, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
817:19x 43
721:7x 103
591:3x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 221412388932/(1x3)
LCM = 221412388932/3
LCM = 73804129644
Thus, we can understand that the LCM of 636,817,721,591 is 73804129644.
