Given numbers are 422,899,390

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

The LCM of 422,899,390 is 73978710.

Find LCM of 422,899,390 with Prime Factorization

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

2 x 211 x 899 x 195 = 73978710

Therefore, the lowest common multiple of 422,899,390 is 73978710.

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 899 x 390 = 147957420

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

899 : 1, 29, 31, 899

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,899,390, is 1.

Now, the common factors can be found like this.

422:2x 211

899:29x 31

390:2x 3x 5x 13

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 = 147957420/(1x2)

LCM = 147957420/2

LCM = 73978710

Thus, we can understand that the LCM of 422,899,390 is 73978710.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 423, 920, 309
