Given numbers are 842,654,787,122

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

The LCM of 842,654,787,122 is 13217959338.

Find LCM of 842,654,787,122 with Prime Factorization

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

2 x 421 x 327 x 787 x 61 = 13217959338

Therefore, the lowest common multiple of 842,654,787,122 is 13217959338.

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.

842 x 654 x 787 x 122 = 52871837352

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.

842 : 1, 2, 421, 842

654 : 1, 2, 3, 6, 109, 218, 327, 654

787 : 1, 787

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,654,787,122, is 1.

Now, the common factors can be found like this.

842:2x 421

654:2x 3x 109

787:787

122:2x 61

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 52871837352/(1x4)

LCM = 52871837352/4

LCM = 13217959338

Thus, we can understand that the LCM of 842,654,787,122 is 13217959338.
