Given numbers are 667,221,391,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,221,391,515 is 75914605.
Find LCM of 667,221,391,515 with Prime Factorization
17 | 667, 221, 391, 515 |
23 | 667, 13, 23, 515 |
29, 13, 1, 515 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 29 x 13 x 1 x 515 = 75914605
Therefore, the lowest common multiple of 667,221,391,515 is 75914605.
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 221 x 391 x 515 = 29682610555
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
221 : 1, 13, 17, 221
391 : 1, 17, 23, 391
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,221,391,515, is 1.
Now, the common factors can be found like this.
667:23x 29
221:13x 17
391:17x 23
515:5x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 29682610555/(1x391)
LCM = 29682610555/391
LCM = 75914605
Thus, we can understand that the LCM of 667,221,391,515 is 75914605.
