Given numbers are 721,206,823,355

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

The LCM of 721,206,823,355 is 421301930.

Find LCM of 721,206,823,355 with Prime Factorization

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

103 x 7 x 2 x 823 x 355 = 421301930

Therefore, the lowest common multiple of 721,206,823,355 is 421301930.

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.

721 x 206 x 823 x 355 = 43394098790

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.

721 : 1, 7, 103, 721

206 : 1, 2, 103, 206

823 : 1, 823

355 : 1, 5, 71, 355

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,206,823,355, is 1.

Now, the common factors can be found like this.

721:7x 103

206:2x 103

823:823

355:5x 71

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

103 = 103

Therefore, the value for common factors is 103.

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 = 43394098790/(1x103)

LCM = 43394098790/103

LCM = 421301930

Thus, we can understand that the LCM of 721,206,823,355 is 421301930.
