Given numbers are 429,986,860,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,986,860,990 is 545662260.
Find LCM of 429,986,860,990 with Prime Factorization
| 2 | 429, 986, 860, 990 |
| 3 | 429, 493, 430, 495 |
| 5 | 143, 493, 430, 165 |
| 11 | 143, 493, 86, 33 |
| 13, 493, 86, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 493 x 86 x 3 = 545662260
Therefore, the lowest common multiple of 429,986,860,990 is 545662260.
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.
429 x 986 x 860 x 990 = 360137091600
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
986 : 1, 2, 17, 29, 34, 58, 493, 986
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,986,860,990, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
986:2x 17x 29
860:2x 2x 5x 43
990:2x 3x 3x 5x 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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 360137091600/(1x660)
LCM = 360137091600/660
LCM = 545662260
Thus, we can understand that the LCM of 429,986,860,990 is 545662260.
