Given numbers are 638,334,412,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,334,412,318 is 3489807684.
Find LCM of 638,334,412,318 with Prime Factorization
2 | 638, 334, 412, 318 |
319, 167, 206, 159 |
Multiply the prime numbers at the bottom and the left side.
2 x 319 x 167 x 206 x 159 = 3489807684
Therefore, the lowest common multiple of 638,334,412,318 is 3489807684.
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 334 x 412 x 318 = 27918461472
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
334 : 1, 2, 167, 334
412 : 1, 2, 4, 103, 206, 412
318 : 1, 2, 3, 6, 53, 106, 159, 318
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,334,412,318, is 2.
Now, the common factors can be found like this.
638:2x 11x 29
334:2x 167
412:2x 2x 103
318:2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 27918461472/(2x4)
LCM = 27918461472/8
LCM = 3489807684
Thus, we can understand that the LCM of 638,334,412,318 is 3489807684.
