Given numbers are 717,432,156,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,432,156,400 is 33555600.
Find LCM of 717,432,156,400 with Prime Factorization
| 2 | 717, 432, 156, 400 |
| 2 | 717, 216, 78, 200 |
| 2 | 717, 108, 39, 100 |
| 2 | 717, 54, 39, 50 |
| 3 | 717, 27, 39, 25 |
| 239, 9, 13, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 239 x 9 x 13 x 25 = 33555600
Therefore, the lowest common multiple of 717,432,156,400 is 33555600.
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.
717 x 432 x 156 x 400 = 19328025600
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.
717 : 1, 3, 239, 717
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,432,156,400, is 1.
Now, the common factors can be found like this.
717:3x 239
432:2x 2x 2x 2x 3x 3x 3
156:2x 2x 3x 13
400:2x 2x 2x 2x 5x 5
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 2x 2x 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 19328025600/(1x576)
LCM = 19328025600/576
LCM = 33555600
Thus, we can understand that the LCM of 717,432,156,400 is 33555600.
