Given numbers are 705,206,161,722

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

The LCM of 705,206,161,722 is 8440912830.

Find LCM of 705,206,161,722 with Prime Factorization

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

2 x 705 x 103 x 161 x 361 = 8440912830

Therefore, the lowest common multiple of 705,206,161,722 is 8440912830.

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.

705 x 206 x 161 x 722 = 16881825660

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

206 : 1, 2, 103, 206

161 : 1, 7, 23, 161

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,206,161,722, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

206:2x 103

161:7x 23

722:2x 19x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 16881825660/(1x2)

LCM = 16881825660/2

LCM = 8440912830

Thus, we can understand that the LCM of 705,206,161,722 is 8440912830.
