Given numbers are 403,776,388,990

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

The LCM of 403,776,388,990 is 154800360.

Find LCM of 403,776,388,990 with Prime Factorization

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

2 x 2 x 97 x 403 x 1 x 2 x 495 = 154800360

Therefore, the lowest common multiple of 403,776,388,990 is 154800360.

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.

403 x 776 x 388 x 990 = 120125079360

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.

403 : 1, 13, 31, 403

776 : 1, 2, 4, 8, 97, 194, 388, 776

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,776,388,990, is 1.

Now, the common factors can be found like this.

403:13x 31

776:2x 2x 2x 97

388:2x 2x 97

990:2x 3x 3x 5x 11

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

2x 2x 2x 97 = 776

Therefore, the value for common factors is 776.

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 = 120125079360/(1x776)

LCM = 120125079360/776

LCM = 154800360

Thus, we can understand that the LCM of 403,776,388,990 is 154800360.
