Given numbers are 422,209,618,340

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

The LCM of 422,209,618,340 is 4633040940.

Find LCM of 422,209,618,340 with Prime Factorization

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

2 x 211 x 209 x 309 x 170 = 4633040940

Therefore, the lowest common multiple of 422,209,618,340 is 4633040940.

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.

422 x 209 x 618 x 340 = 18532163760

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.

422 : 1, 2, 211, 422

209 : 1, 11, 19, 209

618 : 1, 2, 3, 6, 103, 206, 309, 618

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,209,618,340, is 1.

Now, the common factors can be found like this.

422:2x 211

209:11x 19

618:2x 3x 103

340:2x 2x 5x 17

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 = 18532163760/(1x4)

LCM = 18532163760/4

LCM = 4633040940

Thus, we can understand that the LCM of 422,209,618,340 is 4633040940.
