Calculate the LCM of 818,598,621,422

Given numbers are 818,598,621,422

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

The LCM of 818,598,621,422 is 1393383654.

Find LCM of 818,598,621,422 with Prime Factorization


2 818, 598, 621, 422
23 409, 299, 621, 211
409, 13, 27, 211

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

2 x 23 x 409 x 13 x 27 x 211 = 1393383654

Therefore, the lowest common multiple of 818,598,621,422 is 1393383654.

LCM Formula to Find Lowest Common Multiple of 818,598,621,422

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.

818 x 598 x 621 x 422 = 128191296168

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.

818 : 1, 2, 409, 818

598 : 1, 2, 13, 23, 26, 46, 299, 598

621 : 1, 3, 9, 23, 27, 69, 207, 621

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,598,621,422, is 1.

Now, the common factors can be found like this.

818:2x 409

598:2x 13x 23

621:3x 3x 3x 23

422:2x 211

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

2x 2x 23 = 92

Therefore, the value for common factors is 92.

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 = 128191296168/(1x92)

LCM = 128191296168/92

LCM = 1393383654

Thus, we can understand that the LCM of 818,598,621,422 is 1393383654.
