Given numbers are 612,646,626,568
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,646,626,568 is 516818088.
Find LCM of 612,646,626,568 with Prime Factorization
| 2 | 612, 646, 626, 568 |
| 2 | 306, 323, 313, 284 |
| 17 | 153, 323, 313, 142 |
| 9, 19, 313, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 9 x 19 x 313 x 142 = 516818088
Therefore, the lowest common multiple of 612,646,626,568 is 516818088.
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.
612 x 646 x 626 x 568 = 140574519936
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
646 : 1, 2, 17, 19, 34, 38, 323, 646
626 : 1, 2, 313, 626
568 : 1, 2, 4, 8, 71, 142, 284, 568
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,646,626,568, is 2.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
646:2x 17x 19
626:2x 313
568:2x 2x 2x 71
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 17 = 136
Therefore, the value for common factors is 136.
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 = 140574519936/(2x136)
LCM = 140574519936/272
LCM = 516818088
Thus, we can understand that the LCM of 612,646,626,568 is 516818088.
