Given numbers are 873,780,432,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,780,432,670 is 182491920.
Find LCM of 873,780,432,670 with Prime Factorization
| 2 | 873, 780, 432, 670 |
| 2 | 873, 390, 216, 335 |
| 3 | 873, 195, 108, 335 |
| 3 | 291, 65, 36, 335 |
| 5 | 97, 65, 12, 335 |
| 97, 13, 12, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 97 x 13 x 12 x 67 = 182491920
Therefore, the lowest common multiple of 873,780,432,670 is 182491920.
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.
873 x 780 x 432 x 670 = 197091273600
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.
873 : 1, 3, 9, 97, 291, 873
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,780,432,670, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
780:2x 2x 3x 5x 13
432:2x 2x 2x 2x 3x 3x 3
670:2x 5x 67
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 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 197091273600/(1x1080)
LCM = 197091273600/1080
LCM = 182491920
Thus, we can understand that the LCM of 873,780,432,670 is 182491920.
