Given numbers are 456,285,429,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 456,285,429,630 is 6846840.
Find LCM of 456,285,429,630 with Prime Factorization
| 2 | 456, 285, 429, 630 |
| 3 | 228, 285, 429, 315 |
| 5 | 76, 95, 143, 105 |
| 19 | 76, 19, 143, 21 |
| 4, 1, 143, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 4 x 1 x 143 x 21 = 6846840
Therefore, the lowest common multiple of 456,285,429,630 is 6846840.
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.
456 x 285 x 429 x 630 = 35124289200
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
285 : 1, 3, 5, 15, 19, 57, 95, 285
429 : 1, 3, 11, 13, 33, 39, 143, 429
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
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,285,429,630, is 3.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
285:3x 5x 19
429:3x 11x 13
630:2x 3x 3x 5x 7
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 5x 19 = 1710
Therefore, the value for common factors is 1710.
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 = 35124289200/(3x1710)
LCM = 35124289200/5130
LCM = 6846840
Thus, we can understand that the LCM of 456,285,429,630 is 6846840.
