Given numbers are 647,214,954,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,214,954,402 is 4424979222.
Find LCM of 647,214,954,402 with Prime Factorization
| 2 | 647, 214, 954, 402 |
| 3 | 647, 107, 477, 201 |
| 647, 107, 159, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 647 x 107 x 159 x 67 = 4424979222
Therefore, the lowest common multiple of 647,214,954,402 is 4424979222.
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.
647 x 214 x 954 x 402 = 53099750664
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.
647 : 1, 647
214 : 1, 2, 107, 214
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,214,954,402, is 1.
Now, the common factors can be found like this.
647:647
214:2x 107
954:2x 3x 3x 53
402:2x 3x 67
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 3 = 12
Therefore, the value for common factors is 12.
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 = 53099750664/(1x12)
LCM = 53099750664/12
LCM = 4424979222
Thus, we can understand that the LCM of 647,214,954,402 is 4424979222.
