Given numbers are 859,678,780,689,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,678,780,689,621 is 830639204460.
Find LCM of 859,678,780,689,621 with Prime Factorization
| 2 | 859, 678, 780, 689, 621 |
| 3 | 859, 339, 390, 689, 621 |
| 13 | 859, 113, 130, 689, 207 |
| 859, 113, 10, 53, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 859 x 113 x 10 x 53 x 207 = 830639204460
Therefore, the lowest common multiple of 859,678,780,689,621 is 830639204460.
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.
859 x 678 x 780 x 689 x 621 = 194369573843640
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.
859 : 1, 859
678 : 1, 2, 3, 6, 113, 226, 339, 678
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
689 : 1, 13, 53, 689
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,678,780,689,621, is 1.
Now, the common factors can be found like this.
859:859
678:2x 3x 113
780:2x 2x 3x 5x 13
689:13x 53
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 194369573843640/(1x234)
LCM = 194369573843640/234
LCM = 830639204460
Thus, we can understand that the LCM of 859,678,780,689,621 is 830639204460.
