Given numbers are 685,321,133,608

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

The LCM of 685,321,133,608 is 935830560.

Find LCM of 685,321,133,608 with Prime Factorization

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

19 x 685 x 321 x 7 x 32 = 935830560

Therefore, the lowest common multiple of 685,321,133,608 is 935830560.

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 321 x 133 x 608 = 17780780640

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

321 : 1, 3, 107, 321

133 : 1, 7, 19, 133

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,321,133,608, is 1.

Now, the common factors can be found like this.

685:5x 137

321:3x 107

133:7x 19

608:2x 2x 2x 2x 2x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 17780780640/(1x19)

LCM = 17780780640/19

LCM = 935830560

Thus, we can understand that the LCM of 685,321,133,608 is 935830560.
