Find LCM of 720,906,550,160,636 with Prime Factorization
| 2 | 720, 906, 550, 160, 636 |
| 2 | 360, 453, 275, 80, 318 |
| 2 | 180, 453, 275, 40, 159 |
| 2 | 90, 453, 275, 20, 159 |
| 3 | 45, 453, 275, 10, 159 |
| 5 | 15, 151, 275, 10, 53 |
| 3, 151, 55, 2, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 3 x 151 x 55 x 2 x 53 = 633837600
Therefore, the lowest common multiple of 720,906,550,160,636 is 633837600.
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.
720 x 906 x 550 x 160 x 636 = 36509045760000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
906 : 1, 2, 3, 6, 151, 302, 453, 906
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,906,550,160,636, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
906:2x 3x 151
550:2x 5x 5x 11
160:2x 2x 2x 2x 2x 5
636:2x 2x 3x 53
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 2x 3x 3x 5x 5 = 28800
Therefore, the value for common factors is 28800.
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 = 36509045760000/(2x28800)
LCM = 36509045760000/57600
LCM = 633837600
Thus, we can understand that the LCM of 720,906,550,160,636 is 633837600.
