Given numbers are 487,487,686,455

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

The LCM of 487,487,686,455 is 21715330.

Find LCM of 487,487,686,455 with Prime Factorization

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

7 x 487 x 1 x 1 x 98 x 65 = 21715330

Therefore, the lowest common multiple of 487,487,686,455 is 21715330.

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.

487 x 487 x 686 x 455 = 74027559970

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.

487 : 1, 487

487 : 1, 487

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,487,686,455, is 1.

Now, the common factors can be found like this.

487:487

487:487

686:2x 7x 7x 7

455:5x 7x 13

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

7x 487 = 3409

Therefore, the value for common factors is 3409.

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 = 74027559970/(1x3409)

LCM = 74027559970/3409

LCM = 21715330

Thus, we can understand that the LCM of 487,487,686,455 is 21715330.
