Given numbers are 122,687,748,385

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

The LCM of 122,687,748,385 is 1097125260.

Find LCM of 122,687,748,385 with Prime Factorization

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

2 x 11 x 61 x 687 x 34 x 35 = 1097125260

Therefore, the lowest common multiple of 122,687,748,385 is 1097125260.

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.

122 x 687 x 748 x 385 = 24136755720

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.

122 : 1, 2, 61, 122

687 : 1, 3, 229, 687

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,687,748,385, is 1.

Now, the common factors can be found like this.

122:2x 61

687:3x 229

748:2x 2x 11x 17

385:5x 7x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 24136755720/(1x22)

LCM = 24136755720/22

LCM = 1097125260

Thus, we can understand that the LCM of 122,687,748,385 is 1097125260.
