Given numbers are 718,669,990,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,669,990,429 is 1030333590.
Find LCM of 718,669,990,429 with Prime Factorization
| 2 | 718, 669, 990, 429 |
| 3 | 359, 669, 495, 429 |
| 11 | 359, 223, 165, 143 |
| 359, 223, 15, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 359 x 223 x 15 x 13 = 1030333590
Therefore, the lowest common multiple of 718,669,990,429 is 1030333590.
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.
718 x 669 x 990 x 429 = 204006050820
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.
718 : 1, 2, 359, 718
669 : 1, 3, 223, 669
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,669,990,429, is 1.
Now, the common factors can be found like this.
718:2x 359
669:3x 223
990:2x 3x 3x 5x 11
429:3x 11x 13
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 11 = 198
Therefore, the value for common factors is 198.
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 = 204006050820/(1x198)
LCM = 204006050820/198
LCM = 1030333590
Thus, we can understand that the LCM of 718,669,990,429 is 1030333590.
