Given numbers are 720,906,372,604
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,906,372,604 is 3370320.
Find LCM of 720,906,372,604 with Prime Factorization
| 2 | 720, 906, 372, 604 |
| 2 | 360, 453, 186, 302 |
| 3 | 180, 453, 93, 151 |
| 151 | 60, 151, 31, 151 |
| 60, 1, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 151 x 60 x 1 x 31 x 1 = 3370320
Therefore, the lowest common multiple of 720,906,372,604 is 3370320.
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.
720 x 906 x 372 x 604 = 146568476160
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
906 : 1, 2, 3, 6, 151, 302, 453, 906
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
604 : 1, 2, 4, 151, 302, 604
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,906,372,604, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
906:2x 3x 151
372:2x 2x 3x 31
604:2x 2x 151
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 3x 3x 151 = 21744
Therefore, the value for common factors is 21744.
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 = 146568476160/(2x21744)
LCM = 146568476160/43488
LCM = 3370320
Thus, we can understand that the LCM of 720,906,372,604 is 3370320.
