Given numbers are 685,803,168,511

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

The LCM of 685,803,168,511 is 92409240.

Find LCM of 685,803,168,511 with Prime Factorization

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

7 x 73 x 685 x 11 x 24 x 1 = 92409240

Therefore, the lowest common multiple of 685,803,168,511 is 92409240.

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 803 x 168 x 511 = 47221121640

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

803 : 1, 11, 73, 803

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

511 : 1, 7, 73, 511

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,803,168,511, is 1.

Now, the common factors can be found like this.

685:5x 137

803:11x 73

168:2x 2x 2x 3x 7

511:7x 73

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

7x 73 = 511

Therefore, the value for common factors is 511.

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 = 47221121640/(1x511)

LCM = 47221121640/511

LCM = 92409240

Thus, we can understand that the LCM of 685,803,168,511 is 92409240.
