Find LCM of 155,443,756,900,770 with Prime Factorization
| 2 | 155, 443, 756, 900, 770 |
| 2 | 155, 443, 378, 450, 385 |
| 3 | 155, 443, 189, 225, 385 |
| 3 | 155, 443, 63, 75, 385 |
| 5 | 155, 443, 21, 25, 385 |
| 7 | 31, 443, 21, 5, 77 |
| 31, 443, 3, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 31 x 443 x 3 x 5 x 11 = 2855090700
Therefore, the lowest common multiple of 155,443,756,900,770 is 2855090700.
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.
155 x 443 x 756 x 900 x 770 = 35974142820000
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.
155 : 1, 5, 31, 155
443 : 1, 443
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,443,756,900,770, is 1.
Now, the common factors can be found like this.
155:5x 31
443:443
756:2x 2x 3x 3x 3x 7
900:2x 2x 3x 3x 5x 5
770:2x 5x 7x 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 5x 5x 7 = 12600
Therefore, the value for common factors is 12600.
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 = 35974142820000/(1x12600)
LCM = 35974142820000/12600
LCM = 2855090700
Thus, we can understand that the LCM of 155,443,756,900,770 is 2855090700.
