Calculate the LCM of 821,801,356,246

Given numbers are 821,801,356,246

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

The LCM of 821,801,356,246 is 107849844.

Find LCM of 821,801,356,246 with Prime Factorization


2 821, 801, 356, 246
3 821, 801, 178, 123
89 821, 267, 178, 41
821, 3, 2, 41

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

2 x 3 x 89 x 821 x 3 x 2 x 41 = 107849844

Therefore, the lowest common multiple of 821,801,356,246 is 107849844.

LCM Formula to Find Lowest Common Multiple of 821,801,356,246

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.

821 x 801 x 356 x 246 = 57591816696

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.

821 : 1, 821

801 : 1, 3, 9, 89, 267, 801

356 : 1, 2, 4, 89, 178, 356

246 : 1, 2, 3, 6, 41, 82, 123, 246

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,801,356,246, is 1.

Now, the common factors can be found like this.

821:821

801:3x 3x 89

356:2x 2x 89

246:2x 3x 41

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

2x 3x 89 = 534

Therefore, the value for common factors is 534.

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 = 57591816696/(1x534)

LCM = 57591816696/534

LCM = 107849844

Thus, we can understand that the LCM of 821,801,356,246 is 107849844.
