Given numbers are 163,722,813,321,661

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

The LCM of 163,722,813,321,661 is 6767068687986.

Find LCM of 163,722,813,321,661 with Prime Factorization

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

3 x 163 x 722 x 271 x 107 x 661 = 6767068687986

Therefore, the lowest common multiple of 163,722,813,321,661 is 6767068687986.

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.

163 x 722 x 813 x 321 x 661 = 20301206063958

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.

163 : 1, 163

722 : 1, 2, 19, 38, 361, 722

813 : 1, 3, 271, 813

321 : 1, 3, 107, 321

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,722,813,321,661, is 1.

Now, the common factors can be found like this.

163:163

722:2x 19x 19

813:3x 271

321:3x 107

661:661

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

3 = 3

Therefore, the value for common factors is 3.

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 = 20301206063958/(1x3)

LCM = 20301206063958/3

LCM = 6767068687986

Thus, we can understand that the LCM of 163,722,813,321,661 is 6767068687986.
