Given numbers are 180,698,686,864,540

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

The LCM of 180,698,686,864,540 is 517134240.

Find LCM of 180,698,686,864,540 with Prime Factorization

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

2 x 2 x 3 x 3 x 3 x 5 x 1 x 349 x 343 x 8 x 1 = 517134240

Therefore, the lowest common multiple of 180,698,686,864,540 is 517134240.

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.

180 x 698 x 686 x 864 x 540 = 40212358502400

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.

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

698 : 1, 2, 349, 698

686 : 1, 2, 7, 14, 49, 98, 343, 686

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,698,686,864,540, is 2.

Now, the common factors can be found like this.

180:2x 2x 3x 3x 5

698:2x 349

686:2x 7x 7x 7

864:2x 2x 2x 2x 2x 3x 3x 3

540:2x 2x 3x 3x 3x 5

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

2x 2x 2x 2x 2x 3x 3x 3x 3x 3x 5 = 38880

Therefore, the value for common factors is 38880.

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 = 40212358502400/(2x38880)

LCM = 40212358502400/77760

LCM = 517134240

Thus, we can understand that the LCM of 180,698,686,864,540 is 517134240.
