Given numbers are 656,687,690,444,267
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 656,687,690,444,267 is 170667233040.
Find LCM of 656,687,690,444,267 with Prime Factorization
| 2 | 656, 687, 690, 444, 267 |
| 2 | 328, 687, 345, 222, 267 |
| 3 | 164, 687, 345, 111, 267 |
| 164, 229, 115, 37, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 164 x 229 x 115 x 37 x 89 = 170667233040
Therefore, the lowest common multiple of 656,687,690,444,267 is 170667233040.
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.
656 x 687 x 690 x 444 x 267 = 36864122336640
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.
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
687 : 1, 3, 229, 687
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
267 : 1, 3, 89, 267
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,687,690,444,267, is 1.
Now, the common factors can be found like this.
656:2x 2x 2x 2x 41
687:3x 229
690:2x 3x 5x 23
444:2x 2x 3x 37
267:3x 89
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 36864122336640/(1x216)
LCM = 36864122336640/216
LCM = 170667233040
Thus, we can understand that the LCM of 656,687,690,444,267 is 170667233040.
