Given numbers are 806,707,658,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,707,658,646 is 8650771402.
Find LCM of 806,707,658,646 with Prime Factorization
2 | 806, 707, 658, 646 |
7 | 403, 707, 329, 323 |
403, 101, 47, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 403 x 101 x 47 x 323 = 8650771402
Therefore, the lowest common multiple of 806,707,658,646 is 8650771402.
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.
806 x 707 x 658 x 646 = 242221599256
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
707 : 1, 7, 101, 707
658 : 1, 2, 7, 14, 47, 94, 329, 658
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,707,658,646, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
707:7x 101
658:2x 7x 47
646:2x 17x 19
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 7 = 28
Therefore, the value for common factors is 28.
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 = 242221599256/(1x28)
LCM = 242221599256/28
LCM = 8650771402
Thus, we can understand that the LCM of 806,707,658,646 is 8650771402.
