Given numbers are 388,236,221,552,728

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

The LCM of 388,236,221,552,728 is 4887121512.

Find LCM of 388,236,221,552,728 with Prime Factorization

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

2 x 2 x 2 x 13 x 97 x 59 x 17 x 69 x 7 = 4887121512

Therefore, the lowest common multiple of 388,236,221,552,728 is 4887121512.

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 236 x 221 x 552 x 728 = 8132170195968

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

236 : 1, 2, 4, 59, 118, 236

221 : 1, 13, 17, 221

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,236,221,552,728, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

236:2x 2x 59

221:13x 17

552:2x 2x 2x 3x 23

728:2x 2x 2x 7x 13

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 2x 2x 2x 13 = 1664

Therefore, the value for common factors is 1664.

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 = 8132170195968/(1x1664)

LCM = 8132170195968/1664

LCM = 4887121512

Thus, we can understand that the LCM of 388,236,221,552,728 is 4887121512.
