Calculate the LCM of 621,253,422,155

Given numbers are 621,253,422,155

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

The LCM of 621,253,422,155 is 446815710.

Find LCM of 621,253,422,155 with Prime Factorization


23 621, 253, 422, 155
27, 11, 422, 155

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

23 x 27 x 11 x 422 x 155 = 446815710

Therefore, the lowest common multiple of 621,253,422,155 is 446815710.

LCM Formula to Find Lowest Common Multiple of 621,253,422,155

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.

621 x 253 x 422 x 155 = 10276761330

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.

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

253 : 1, 11, 23, 253

422 : 1, 2, 211, 422

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,253,422,155, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

253:11x 23

422:2x 211

155:5x 31

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

23 = 23

Therefore, the value for common factors is 23.

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 = 10276761330/(1x23)

LCM = 10276761330/23

LCM = 446815710

Thus, we can understand that the LCM of 621,253,422,155 is 446815710.
