Given numbers are 685,218,654,199

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

The LCM of 685,218,654,199 is 89150010.

Find LCM of 685,218,654,199 with Prime Factorization

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

2 x 109 x 685 x 1 x 3 x 199 = 89150010

Therefore, the lowest common multiple of 685,218,654,199 is 89150010.

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.

685 x 218 x 654 x 199 = 19434702180

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.

685 : 1, 5, 137, 685

218 : 1, 2, 109, 218

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

199 : 1, 199

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,218,654,199, is 1.

Now, the common factors can be found like this.

685:5x 137

218:2x 109

654:2x 3x 109

199:199

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 19434702180/(1x218)

LCM = 19434702180/218

LCM = 89150010

Thus, we can understand that the LCM of 685,218,654,199 is 89150010.
