Given numbers are 971,640,206,722

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

The LCM of 971,640,206,722 is 23107003520.

Find LCM of 971,640,206,722 with Prime Factorization

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

2 x 971 x 320 x 103 x 361 = 23107003520

Therefore, the lowest common multiple of 971,640,206,722 is 23107003520.

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.

971 x 640 x 206 x 722 = 92428014080

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.

971 : 1, 971

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

206 : 1, 2, 103, 206

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 971,640,206,722, is 1.

Now, the common factors can be found like this.

971:971

640:2x 2x 2x 2x 2x 2x 2x 5

206:2x 103

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 92428014080/(1x4)

LCM = 92428014080/4

LCM = 23107003520

Thus, we can understand that the LCM of 971,640,206,722 is 23107003520.
