Given numbers are 516,636,874,341,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,636,874,341,420 is 142636092060.
Find LCM of 516,636,874,341,420 with Prime Factorization
| 2 | 516, 636, 874, 341, 420 |
| 2 | 258, 318, 437, 341, 210 |
| 3 | 129, 159, 437, 341, 105 |
| 43, 53, 437, 341, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 53 x 437 x 341 x 35 = 142636092060
Therefore, the lowest common multiple of 516,636,874,341,420 is 142636092060.
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.
516 x 636 x 874 x 341 x 420 = 41079194513280
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
874 : 1, 2, 19, 23, 38, 46, 437, 874
341 : 1, 11, 31, 341
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,636,874,341,420, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
636:2x 2x 3x 53
874:2x 19x 23
341:11x 31
420:2x 2x 3x 5x 7
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 2x 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 41079194513280/(1x288)
LCM = 41079194513280/288
LCM = 142636092060
Thus, we can understand that the LCM of 516,636,874,341,420 is 142636092060.
