Given numbers are 122,122,631,820

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

The LCM of 122,122,631,820 is 31562620.

Find LCM of 122,122,631,820 with Prime Factorization

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

2 x 61 x 1 x 1 x 631 x 410 = 31562620

Therefore, the lowest common multiple of 122,122,631,820 is 31562620.

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 122 x 631 x 820 = 7701279280

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

122 : 1, 2, 61, 122

631 : 1, 631

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,122,631,820, is 1.

Now, the common factors can be found like this.

122:2x 61

122:2x 61

631:631

820:2x 2x 5x 41

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 61 = 244

Therefore, the value for common factors is 244.

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 = 7701279280/(1x244)

LCM = 7701279280/244

LCM = 31562620

Thus, we can understand that the LCM of 122,122,631,820 is 31562620.
