Given numbers are 120,630,165,471,633
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,630,165,471,633 is 918280440.
Find LCM of 120,630,165,471,633 with Prime Factorization
| 2 | 120, 630, 165, 471, 633 |
| 3 | 60, 315, 165, 471, 633 |
| 5 | 20, 105, 55, 157, 211 |
| 4, 21, 11, 157, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 4 x 21 x 11 x 157 x 211 = 918280440
Therefore, the lowest common multiple of 120,630,165,471,633 is 918280440.
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.
120 x 630 x 165 x 471 x 633 = 3719035782000
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
165 : 1, 3, 5, 11, 15, 33, 55, 165
471 : 1, 3, 157, 471
633 : 1, 3, 211, 633
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,630,165,471,633, is 3.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
630:2x 3x 3x 5x 7
165:3x 5x 11
471:3x 157
633:3x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 3719035782000/(3x1350)
LCM = 3719035782000/4050
LCM = 918280440
Thus, we can understand that the LCM of 120,630,165,471,633 is 918280440.
