Given numbers are 388,840,689,242

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

The LCM of 388,840,689,242 is 6792906120.

Find LCM of 388,840,689,242 with Prime Factorization

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

2 x 2 x 97 x 210 x 689 x 121 = 6792906120

Therefore, the lowest common multiple of 388,840,689,242 is 6792906120.

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 840 x 689 x 242 = 54343248960

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

689 : 1, 13, 53, 689

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,840,689,242, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

840:2x 2x 2x 3x 5x 7

689:13x 53

242:2x 11x 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 2 = 8

Therefore, the value for common factors is 8.

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 = 54343248960/(1x8)

LCM = 54343248960/8

LCM = 6792906120

Thus, we can understand that the LCM of 388,840,689,242 is 6792906120.
