Given numbers are 363,353,388,620

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

The LCM of 363,353,388,620 is 7706279460.

Find LCM of 363,353,388,620 with Prime Factorization

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

2 x 2 x 363 x 353 x 97 x 155 = 7706279460

Therefore, the lowest common multiple of 363,353,388,620 is 7706279460.

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.

363 x 353 x 388 x 620 = 30825117840

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.

363 : 1, 3, 11, 33, 121, 363

353 : 1, 353

388 : 1, 2, 4, 97, 194, 388

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,353,388,620, is 1.

Now, the common factors can be found like this.

363:3x 11x 11

353:353

388:2x 2x 97

620:2x 2x 5x 31

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 = 30825117840/(1x4)

LCM = 30825117840/4

LCM = 7706279460

Thus, we can understand that the LCM of 363,353,388,620 is 7706279460.
