Given numbers are 422,420,714,934,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,420,714,934,647 is 455199554460.
Find LCM of 422,420,714,934,647 with Prime Factorization
| 2 | 422, 420, 714, 934, 647 |
| 3 | 211, 210, 357, 467, 647 |
| 7 | 211, 70, 119, 467, 647 |
| 211, 10, 17, 467, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 211 x 10 x 17 x 467 x 647 = 455199554460
Therefore, the lowest common multiple of 422,420,714,934,647 is 455199554460.
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.
422 x 420 x 714 x 934 x 647 = 76473525149280
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.
422 : 1, 2, 211, 422
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
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
934 : 1, 2, 467, 934
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,420,714,934,647, is 1.
Now, the common factors can be found like this.
422:2x 211
420:2x 2x 3x 5x 7
714:2x 3x 7x 17
934:2x 467
647:647
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 76473525149280/(1x168)
LCM = 76473525149280/168
LCM = 455199554460
Thus, we can understand that the LCM of 422,420,714,934,647 is 455199554460.
