Given numbers are 457,345,686,226

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

The LCM of 457,345,686,226 is 12221875470.

Find LCM of 457,345,686,226 with Prime Factorization

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

2 x 457 x 345 x 343 x 113 = 12221875470

Therefore, the lowest common multiple of 457,345,686,226 is 12221875470.

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.

457 x 345 x 686 x 226 = 24443750940

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.

457 : 1, 457

345 : 1, 3, 5, 15, 23, 69, 115, 345

686 : 1, 2, 7, 14, 49, 98, 343, 686

226 : 1, 2, 113, 226

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,345,686,226, is 1.

Now, the common factors can be found like this.

457:457

345:3x 5x 23

686:2x 7x 7x 7

226:2x 113

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 = 24443750940/(1x2)

LCM = 24443750940/2

LCM = 12221875470

Thus, we can understand that the LCM of 457,345,686,226 is 12221875470.
