Calculate the LCM of 817,217,961,404

Given numbers are 817,217,961,404

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

The LCM of 817,217,961,404 is 2220367436.

Find LCM of 817,217,961,404 with Prime Factorization


31 817, 217, 961, 404
817, 7, 31, 404

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

31 x 817 x 7 x 31 x 404 = 2220367436

Therefore, the lowest common multiple of 817,217,961,404 is 2220367436.

LCM Formula to Find Lowest Common Multiple of 817,217,961,404

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 217 x 961 x 404 = 68831390516

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

217 : 1, 7, 31, 217

961 : 1, 31, 961

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,217,961,404, is 1.

Now, the common factors can be found like this.

817:19x 43

217:7x 31

961:31x 31

404:2x 2x 101

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

31 = 31

Therefore, the value for common factors is 31.

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 = 68831390516/(1x31)

LCM = 68831390516/31

LCM = 2220367436

Thus, we can understand that the LCM of 817,217,961,404 is 2220367436.
