Given numbers are 858,572,803,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,572,803,689 is 6639204.
Find LCM of 858,572,803,689 with Prime Factorization
| 2 | 858, 572, 803, 689 |
| 11 | 429, 286, 803, 689 |
| 13 | 39, 26, 73, 689 |
| 3, 2, 73, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 3 x 2 x 73 x 53 = 6639204
Therefore, the lowest common multiple of 858,572,803,689 is 6639204.
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.
858 x 572 x 803 x 689 = 271530165192
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
803 : 1, 11, 73, 803
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,572,803,689, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
572:2x 2x 11x 13
803:11x 73
689:13x 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 11x 11x 13x 13 = 40898
Therefore, the value for common factors is 40898.
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 = 271530165192/(1x40898)
LCM = 271530165192/40898
LCM = 6639204
Thus, we can understand that the LCM of 858,572,803,689 is 6639204.
