Given numbers are 493,990,666,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,990,666,870 is 18058590.
Find LCM of 493,990,666,870 with Prime Factorization
| 2 | 493, 990, 666, 870 |
| 3 | 493, 495, 333, 435 |
| 3 | 493, 165, 111, 145 |
| 5 | 493, 55, 37, 145 |
| 29 | 493, 11, 37, 29 |
| 17, 11, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 29 x 17 x 11 x 37 x 1 = 18058590
Therefore, the lowest common multiple of 493,990,666,870 is 18058590.
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.
493 x 990 x 666 x 870 = 282797519400
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.
493 : 1, 17, 29, 493
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
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,990,666,870, is 1.
Now, the common factors can be found like this.
493:17x 29
990:2x 3x 3x 5x 11
666:2x 3x 3x 37
870:2x 3x 5x 29
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 3x 3x 5x 29 = 15660
Therefore, the value for common factors is 15660.
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 = 282797519400/(1x15660)
LCM = 282797519400/15660
LCM = 18058590
Thus, we can understand that the LCM of 493,990,666,870 is 18058590.
