Given numbers are 655,731,700,628,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,731,700,628,204 is 31572401700.
Find LCM of 655,731,700,628,204 with Prime Factorization
| 2 | 655, 731, 700, 628, 204 |
| 2 | 655, 731, 350, 314, 102 |
| 5 | 655, 731, 175, 157, 51 |
| 17 | 131, 731, 35, 157, 51 |
| 131, 43, 35, 157, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 131 x 43 x 35 x 157 x 3 = 31572401700
Therefore, the lowest common multiple of 655,731,700,628,204 is 31572401700.
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.
655 x 731 x 700 x 628 x 204 = 42938466312000
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.
655 : 1, 5, 131, 655
731 : 1, 17, 43, 731
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
628 : 1, 2, 4, 157, 314, 628
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,731,700,628,204, is 1.
Now, the common factors can be found like this.
655:5x 131
731:17x 43
700:2x 2x 5x 5x 7
628:2x 2x 157
204:2x 2x 3x 17
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 2x 5x 17 = 1360
Therefore, the value for common factors is 1360.
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 = 42938466312000/(1x1360)
LCM = 42938466312000/1360
LCM = 31572401700
Thus, we can understand that the LCM of 655,731,700,628,204 is 31572401700.
