Given numbers are 686,855,821,821,562

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

The LCM of 686,855,821,821,562 is 135313057530.

Find LCM of 686,855,821,821,562 with Prime Factorization

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

2 x 821 x 343 x 855 x 1 x 1 x 281 = 135313057530

Therefore, the lowest common multiple of 686,855,821,821,562 is 135313057530.

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.

686 x 855 x 821 x 821 x 562 = 222184040464260

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.

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

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

821 : 1, 821

821 : 1, 821

562 : 1, 2, 281, 562

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,855,821,821,562, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

855:3x 3x 5x 19

821:821

821:821

562:2x 281

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

2x 821 = 1642

Therefore, the value for common factors is 1642.

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 = 222184040464260/(1x1642)

LCM = 222184040464260/1642

LCM = 135313057530

Thus, we can understand that the LCM of 686,855,821,821,562 is 135313057530.
