Given numbers are 671,342,442,690,117
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,342,442,690,117 is 5832285030.
Find LCM of 671,342,442,690,117 with Prime Factorization
| 2 | 671, 342, 442, 690, 117 |
| 3 | 671, 171, 221, 345, 117 |
| 3 | 671, 57, 221, 115, 39 |
| 13 | 671, 19, 221, 115, 13 |
| 671, 19, 17, 115, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 671 x 19 x 17 x 115 x 1 = 5832285030
Therefore, the lowest common multiple of 671,342,442,690,117 is 5832285030.
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.
671 x 342 x 442 x 690 x 117 = 8188528182120
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.
671 : 1, 11, 61, 671
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
442 : 1, 2, 13, 17, 26, 34, 221, 442
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
117 : 1, 3, 9, 13, 39, 117
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,342,442,690,117, is 1.
Now, the common factors can be found like this.
671:11x 61
342:2x 3x 3x 19
442:2x 13x 17
690:2x 3x 5x 23
117:3x 3x 13
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 3x 3x 3x 13 = 1404
Therefore, the value for common factors is 1404.
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 = 8188528182120/(1x1404)
LCM = 8188528182120/1404
LCM = 5832285030
Thus, we can understand that the LCM of 671,342,442,690,117 is 5832285030.
