Calculate the LCM of 821,172,353,353,859

Given numbers are 821,172,353,353,859

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

The LCM of 821,172,353,353,859 is 42819291124.

Find LCM of 821,172,353,353,859 with Prime Factorization


353 821, 172, 353, 353, 859
821, 172, 1, 1, 859

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

353 x 821 x 172 x 1 x 1 x 859 = 42819291124

Therefore, the lowest common multiple of 821,172,353,353,859 is 42819291124.

LCM Formula to Find Lowest Common Multiple of 821,172,353,353,859

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 172 x 353 x 353 x 859 = 15115209766772

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

172 : 1, 2, 4, 43, 86, 172

353 : 1, 353

353 : 1, 353

859 : 1, 859

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,172,353,353,859, is 1.

Now, the common factors can be found like this.

821:821

172:2x 2x 43

353:353

353:353

859:859

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

353 = 353

Therefore, the value for common factors is 353.

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 = 15115209766772/(1x353)

LCM = 15115209766772/353

LCM = 42819291124

Thus, we can understand that the LCM of 821,172,353,353,859 is 42819291124.
