Find LCM of 909,990,352,921 with Prime Factorization


2 909, 990, 352, 921
3 909, 495, 176, 921
3 303, 165, 176, 307
11 101, 55, 176, 307
101, 5, 16, 307

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

2 x 3 x 3 x 11 x 101 x 5 x 16 x 307 = 491150880

Therefore, the lowest common multiple of 909,990,352,921 is 491150880.

LCM Formula to Find Lowest Common Multiple of 909,990,352,921

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.

909 x 990 x 352 x 921 = 291743622720

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.

909 : 1, 3, 9, 101, 303, 909

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,990,352,921, is 1.

Now, the common factors can be found like this.

909:3x 3x 101

990:2x 3x 3x 5x 11

352:2x 2x 2x 2x 2x 11

921:3x 307

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 3x 3x 11 = 594

Therefore, the value for common factors is 594.

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 = 291743622720/(1x594)

LCM = 291743622720/594

LCM = 491150880

Thus, we can understand that the LCM of 909,990,352,921 is 491150880.
