Given numbers are 388,392,766,802,660

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

The LCM of 388,392,766,802,660 is 963573598680.

Find LCM of 388,392,766,802,660 with Prime Factorization

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

2 x 2 x 97 x 98 x 383 x 401 x 165 = 963573598680

Therefore, the lowest common multiple of 388,392,766,802,660 is 963573598680.

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.

388 x 392 x 766 x 802 x 660 = 61668710315520

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.

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

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

766 : 1, 2, 383, 766

802 : 1, 2, 401, 802

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,392,766,802,660, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

392:2x 2x 2x 7x 7

766:2x 383

802:2x 401

660:2x 2x 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 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 61668710315520/(2x32)

LCM = 61668710315520/64

LCM = 963573598680

Thus, we can understand that the LCM of 388,392,766,802,660 is 963573598680.
