Given numbers are 722,396,406,457

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

The LCM of 722,396,406,457 is 13262171076.

Find LCM of 722,396,406,457 with Prime Factorization

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

2 x 361 x 198 x 203 x 457 = 13262171076

Therefore, the lowest common multiple of 722,396,406,457 is 13262171076.

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.

722 x 396 x 406 x 457 = 53048684304

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.

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

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

406 : 1, 2, 7, 14, 29, 58, 203, 406

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,396,406,457, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

396:2x 2x 3x 3x 11

406:2x 7x 29

457:457

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 = 53048684304/(1x4)

LCM = 53048684304/4

LCM = 13262171076

Thus, we can understand that the LCM of 722,396,406,457 is 13262171076.
