Given numbers are 437,646,342,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,646,342,424 is 28349064.
Find LCM of 437,646,342,424 with Prime Factorization
| 2 | 437, 646, 342, 424 |
| 19 | 437, 323, 171, 212 |
| 23, 17, 9, 212 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 17 x 9 x 212 = 28349064
Therefore, the lowest common multiple of 437,646,342,424 is 28349064.
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.
437 x 646 x 342 x 424 = 40936048416
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.
437 : 1, 19, 23, 437
646 : 1, 2, 17, 19, 34, 38, 323, 646
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,646,342,424, is 1.
Now, the common factors can be found like this.
437:19x 23
646:2x 17x 19
342:2x 3x 3x 19
424:2x 2x 2x 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 2x 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 40936048416/(1x1444)
LCM = 40936048416/1444
LCM = 28349064
Thus, we can understand that the LCM of 437,646,342,424 is 28349064.
