Calculate the LCM of 817,843,516,890

Given numbers are 817,843,516,890

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

The LCM of 817,843,516,890 is 1225941180.

Find LCM of 817,843,516,890 with Prime Factorization


2 817, 843, 516, 890
3 817, 843, 258, 445
43 817, 281, 86, 445
19, 281, 2, 445

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

2 x 3 x 43 x 19 x 281 x 2 x 445 = 1225941180

Therefore, the lowest common multiple of 817,843,516,890 is 1225941180.

LCM Formula to Find Lowest Common Multiple of 817,843,516,890

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.

817 x 843 x 516 x 890 = 316292824440

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.

817 : 1, 19, 43, 817

843 : 1, 3, 281, 843

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,843,516,890, is 1.

Now, the common factors can be found like this.

817:19x 43

843:3x 281

516:2x 2x 3x 43

890:2x 5x 89

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 43 = 258

Therefore, the value for common factors is 258.

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 = 316292824440/(1x258)

LCM = 316292824440/258

LCM = 1225941180

Thus, we can understand that the LCM of 817,843,516,890 is 1225941180.
