Given numbers are 221,130,863,686

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

The LCM of 221,130,863,686 is 654179890.

Find LCM of 221,130,863,686 with Prime Factorization

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

2 x 13 x 17 x 5 x 863 x 343 = 654179890

Therefore, the lowest common multiple of 221,130,863,686 is 654179890.

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.

221 x 130 x 863 x 686 = 17008677140

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.

221 : 1, 13, 17, 221

130 : 1, 2, 5, 10, 13, 26, 65, 130

863 : 1, 863

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,130,863,686, is 1.

Now, the common factors can be found like this.

221:13x 17

130:2x 5x 13

863:863

686:2x 7x 7x 7

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 17008677140/(1x26)

LCM = 17008677140/26

LCM = 654179890

Thus, we can understand that the LCM of 221,130,863,686 is 654179890.
