Given numbers are 479,690,864,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,690,864,660 is 523527840.
Find LCM of 479,690,864,660 with Prime Factorization
| 2 | 479, 690, 864, 660 |
| 2 | 479, 345, 432, 330 |
| 3 | 479, 345, 216, 165 |
| 5 | 479, 115, 72, 55 |
| 479, 23, 72, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 479 x 23 x 72 x 11 = 523527840
Therefore, the lowest common multiple of 479,690,864,660 is 523527840.
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.
479 x 690 x 864 x 660 = 188470022400
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.
479 : 1, 479
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,690,864,660, is 1.
Now, the common factors can be found like this.
479:479
690:2x 3x 5x 23
864:2x 2x 2x 2x 2x 3x 3x 3
660:2x 2x 3x 5x 11
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 188470022400/(1x360)
LCM = 188470022400/360
LCM = 523527840
Thus, we can understand that the LCM of 479,690,864,660 is 523527840.
