Given numbers are 596,645,940,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 596,645,940,655 is 2366873940.
Find LCM of 596,645,940,655 with Prime Factorization
| 2 | 596, 645, 940, 655 |
| 2 | 298, 645, 470, 655 |
| 5 | 149, 645, 235, 655 |
| 149, 129, 47, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 149 x 129 x 47 x 131 = 2366873940
Therefore, the lowest common multiple of 596,645,940,655 is 2366873940.
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.
596 x 645 x 940 x 655 = 236687394000
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.
596 : 1, 2, 4, 149, 298, 596
645 : 1, 3, 5, 15, 43, 129, 215, 645
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 596,645,940,655, is 1.
Now, the common factors can be found like this.
596:2x 2x 149
645:3x 5x 43
940:2x 2x 5x 47
655:5x 131
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 236687394000/(1x100)
LCM = 236687394000/100
LCM = 2366873940
Thus, we can understand that the LCM of 596,645,940,655 is 2366873940.
