Given numbers are 667,431,690,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,431,690,617 is 5321199270.
Find LCM of 667,431,690,617 with Prime Factorization
| 23 | 667, 431, 690, 617 |
| 29, 431, 30, 617 |
Multiply the prime numbers at the bottom and the left side.
23 x 29 x 431 x 30 x 617 = 5321199270
Therefore, the lowest common multiple of 667,431,690,617 is 5321199270.
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.
667 x 431 x 690 x 617 = 122387583210
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.
667 : 1, 23, 29, 667
431 : 1, 431
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,431,690,617, is 1.
Now, the common factors can be found like this.
667:23x 29
431:431
690:2x 3x 5x 23
617:617
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 122387583210/(1x23)
LCM = 122387583210/23
LCM = 5321199270
Thus, we can understand that the LCM of 667,431,690,617 is 5321199270.
