Calculate the LCM of 422,945,387,861

Given numbers are 422,945,387,861

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

The LCM of 422,945,387,861 is 703066770.

Find LCM of 422,945,387,861 with Prime Factorization


3 422, 945, 387, 861
3 422, 315, 129, 287
7 422, 105, 43, 287
422, 15, 43, 41

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

3 x 3 x 7 x 422 x 15 x 43 x 41 = 703066770

Therefore, the lowest common multiple of 422,945,387,861 is 703066770.

LCM Formula to Find Lowest Common Multiple of 422,945,387,861

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 945 x 387 x 861 = 132879619530

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

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

387 : 1, 3, 9, 43, 129, 387

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,945,387,861, is 1.

Now, the common factors can be found like this.

422:2x 211

945:3x 3x 3x 5x 7

387:3x 3x 43

861:3x 7x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 3x 7 = 189

Therefore, the value for common factors is 189.

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 = 132879619530/(1x189)

LCM = 132879619530/189

LCM = 703066770

Thus, we can understand that the LCM of 422,945,387,861 is 703066770.
