Given numbers are 670,846,779,115,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,846,779,115,736 is 81245711520.
Find LCM of 670,846,779,115,736 with Prime Factorization
| 2 | 670, 846, 779, 115, 736 |
| 5 | 335, 423, 779, 115, 368 |
| 23 | 67, 423, 779, 23, 368 |
| 67, 423, 779, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 67 x 423 x 779 x 1 x 16 = 81245711520
Therefore, the lowest common multiple of 670,846,779,115,736 is 81245711520.
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.
670 x 846 x 779 x 115 x 736 = 37373027299200
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
779 : 1, 19, 41, 779
115 : 1, 5, 23, 115
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,846,779,115,736, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
846:2x 3x 3x 47
779:19x 41
115:5x 23
736:2x 2x 2x 2x 2x 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 2x 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 37373027299200/(1x460)
LCM = 37373027299200/460
LCM = 81245711520
Thus, we can understand that the LCM of 670,846,779,115,736 is 81245711520.
