Calculate the LCM of 321,805,851,616

Given numbers are 321,805,851,616

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

The LCM of 321,805,851,616 is 841366680.

Find LCM of 321,805,851,616 with Prime Factorization


7 321, 805, 851, 616
23 321, 115, 851, 88
321, 5, 37, 88

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

7 x 23 x 321 x 5 x 37 x 88 = 841366680

Therefore, the lowest common multiple of 321,805,851,616 is 841366680.

LCM Formula to Find Lowest Common Multiple of 321,805,851,616

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.

321 x 805 x 851 x 616 = 135460035480

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.

321 : 1, 3, 107, 321

805 : 1, 5, 7, 23, 35, 115, 161, 805

851 : 1, 23, 37, 851

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,805,851,616, is 1.

Now, the common factors can be found like this.

321:3x 107

805:5x 7x 23

851:23x 37

616:2x 2x 2x 7x 11

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 135460035480/(1x161)

LCM = 135460035480/161

LCM = 841366680

Thus, we can understand that the LCM of 321,805,851,616 is 841366680.
