Given numbers are 861,218,334,628

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

The LCM of 861,218,334,628 is 9842507724.

Find LCM of 861,218,334,628 with Prime Factorization

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

2 x 861 x 109 x 167 x 314 = 9842507724

Therefore, the lowest common multiple of 861,218,334,628 is 9842507724.

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.

861 x 218 x 334 x 628 = 39370030896

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

218 : 1, 2, 109, 218

334 : 1, 2, 167, 334

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,218,334,628, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

218:2x 109

334:2x 167

628:2x 2x 157

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 = 39370030896/(1x4)

LCM = 39370030896/4

LCM = 9842507724

Thus, we can understand that the LCM of 861,218,334,628 is 9842507724.
