Given numbers are 638,531,452,295

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 638,531,452,295 is 382819140.

Find LCM of 638,531,452,295 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 59 x 319 x 9 x 226 x 5 = 382819140

Therefore, the lowest common multiple of 638,531,452,295 is 382819140.

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 531 x 452 x 295 = 45172658520

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

531 : 1, 3, 9, 59, 177, 531

452 : 1, 2, 4, 113, 226, 452

295 : 1, 5, 59, 295

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,531,452,295, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

531:3x 3x 59

452:2x 2x 113

295:5x 59

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 59 = 118

Therefore, the value for common factors is 118.

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 = 45172658520/(1x118)

LCM = 45172658520/118

LCM = 382819140

Thus, we can understand that the LCM of 638,531,452,295 is 382819140.
