Given numbers are 668,646,646,124,577
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,646,646,124,577 is 3859370668.
Find LCM of 668,646,646,124,577 with Prime Factorization
| 2 | 668, 646, 646, 124, 577 |
| 2 | 334, 323, 323, 62, 577 |
| 17 | 167, 323, 323, 31, 577 |
| 19 | 167, 19, 19, 31, 577 |
| 167, 1, 1, 31, 577 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 167 x 1 x 1 x 31 x 577 = 3859370668
Therefore, the lowest common multiple of 668,646,646,124,577 is 3859370668.
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.
668 x 646 x 646 x 124 x 577 = 19945227612224
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.
668 : 1, 2, 4, 167, 334, 668
646 : 1, 2, 17, 19, 34, 38, 323, 646
646 : 1, 2, 17, 19, 34, 38, 323, 646
124 : 1, 2, 4, 31, 62, 124
577 : 1, 577
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,646,646,124,577, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
646:2x 17x 19
646:2x 17x 19
124:2x 2x 31
577:577
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 2x 2x 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 19945227612224/(1x5168)
LCM = 19945227612224/5168
LCM = 3859370668
Thus, we can understand that the LCM of 668,646,646,124,577 is 3859370668.
