Find LCM of 660,715,540,156 with Prime Factorization
| 2 | 660, 715, 540, 156 |
| 2 | 330, 715, 270, 78 |
| 3 | 165, 715, 135, 39 |
| 5 | 55, 715, 45, 13 |
| 11 | 11, 143, 9, 13 |
| 13 | 1, 13, 9, 13 |
| 1, 1, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 13 x 1 x 1 x 9 x 1 = 77220
Therefore, the lowest common multiple of 660,715,540,156 is 77220.
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.
660 x 715 x 540 x 156 = 39752856000
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.
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,715,540,156, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
715:5x 11x 13
540:2x 2x 3x 3x 3x 5
156:2x 2x 3x 13
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 5x 5x 11x 13 = 514800
Therefore, the value for common factors is 514800.
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 = 39752856000/(1x514800)
LCM = 39752856000/514800
LCM = 77220
Thus, we can understand that the LCM of 660,715,540,156 is 77220.
