Find LCM of 399,328,453,943,990 with Prime Factorization


2 399, 328, 453, 943, 990
3 399, 164, 453, 943, 495
41 133, 164, 151, 943, 165
133, 4, 151, 23, 165

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

2 x 3 x 41 x 133 x 4 x 151 x 23 x 165 = 74995545240

Therefore, the lowest common multiple of 399,328,453,943,990 is 74995545240.

LCM Formula to Find Lowest Common Multiple of 399,328,453,943,990

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.

399 x 328 x 453 x 943 x 990 = 55346712387120

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

328 : 1, 2, 4, 8, 41, 82, 164, 328

453 : 1, 3, 151, 453

943 : 1, 23, 41, 943

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,328,453,943,990, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

328:2x 2x 2x 41

453:3x 151

943:23x 41

990:2x 3x 3x 5x 11

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 41 = 738

Therefore, the value for common factors is 738.

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 = 55346712387120/(1x738)

LCM = 55346712387120/738

LCM = 74995545240

Thus, we can understand that the LCM of 399,328,453,943,990 is 74995545240.
