Given numbers are 906,790,280,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,790,280,315 is 30061080.
Find LCM of 906,790,280,315 with Prime Factorization
| 2 | 906, 790, 280, 315 |
| 3 | 453, 395, 140, 315 |
| 5 | 151, 395, 140, 105 |
| 7 | 151, 79, 28, 21 |
| 151, 79, 4, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 151 x 79 x 4 x 3 = 30061080
Therefore, the lowest common multiple of 906,790,280,315 is 30061080.
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.
906 x 790 x 280 x 315 = 63128268000
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
790 : 1, 2, 5, 10, 79, 158, 395, 790
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,790,280,315, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
790:2x 5x 79
280:2x 2x 2x 5x 7
315:3x 3x 5x 7
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 3x 5x 5x 7 = 2100
Therefore, the value for common factors is 2100.
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 = 63128268000/(1x2100)
LCM = 63128268000/2100
LCM = 30061080
Thus, we can understand that the LCM of 906,790,280,315 is 30061080.
