Given numbers are 660,790,858,606
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,790,858,606 is 68459820.
Find LCM of 660,790,858,606 with Prime Factorization
| 2 | 660, 790, 858, 606 |
| 3 | 330, 395, 429, 303 |
| 5 | 110, 395, 143, 101 |
| 11 | 22, 79, 143, 101 |
| 2, 79, 13, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 2 x 79 x 13 x 101 = 68459820
Therefore, the lowest common multiple of 660,790,858,606 is 68459820.
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.
660 x 790 x 858 x 606 = 271100887200
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
790 : 1, 2, 5, 10, 79, 158, 395, 790
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
606 : 1, 2, 3, 6, 101, 202, 303, 606
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,790,858,606, is 2.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
790:2x 5x 79
858:2x 3x 11x 13
606:2x 3x 101
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 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 271100887200/(2x1980)
LCM = 271100887200/3960
LCM = 68459820
Thus, we can understand that the LCM of 660,790,858,606 is 68459820.
