Given numbers are 638,327,327,565
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,327,327,565 is 117873690.
Find LCM of 638,327,327,565 with Prime Factorization
3 | 638, 327, 327, 565 |
109 | 638, 109, 109, 565 |
638, 1, 1, 565 |
Multiply the prime numbers at the bottom and the left side.
3 x 109 x 638 x 1 x 1 x 565 = 117873690
Therefore, the lowest common multiple of 638,327,327,565 is 117873690.
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.
638 x 327 x 327 x 565 = 38544696630
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
327 : 1, 3, 109, 327
327 : 1, 3, 109, 327
565 : 1, 5, 113, 565
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,327,327,565, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
327:3x 109
327:3x 109
565:5x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 109 = 327
Therefore, the value for common factors is 327.
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 = 38544696630/(1x327)
LCM = 38544696630/327
LCM = 117873690
Thus, we can understand that the LCM of 638,327,327,565 is 117873690.
