Given numbers are 647,494,134,120,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,494,134,120,629 is 808179682440.
Find LCM of 647,494,134,120,629 with Prime Factorization
| 2 | 647, 494, 134, 120, 629 |
| 647, 247, 67, 60, 629 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 247 x 67 x 60 x 629 = 808179682440
Therefore, the lowest common multiple of 647,494,134,120,629 is 808179682440.
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 494 x 134 x 120 x 629 = 3232718729760
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
494 : 1, 2, 13, 19, 26, 38, 247, 494
134 : 1, 2, 67, 134
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,494,134,120,629, is 1.
Now, the common factors can be found like this.
647:647
494:2x 13x 19
134:2x 67
120:2x 2x 2x 3x 5
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 3232718729760/(1x4)
LCM = 3232718729760/4
LCM = 808179682440
Thus, we can understand that the LCM of 647,494,134,120,629 is 808179682440.
