Find LCM of 693,386,934,990 with Prime Factorization


2 693, 386, 934, 990
3 693, 193, 467, 495
3 231, 193, 467, 165
11 77, 193, 467, 55
7, 193, 467, 5

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

2 x 3 x 3 x 11 x 7 x 193 x 467 x 5 = 624607830

Therefore, the lowest common multiple of 693,386,934,990 is 624607830.

LCM Formula to Find Lowest Common Multiple of 693,386,934,990

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.

693 x 386 x 934 x 990 = 247344700680

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.

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

386 : 1, 2, 193, 386

934 : 1, 2, 467, 934

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 693,386,934,990, is 1.

Now, the common factors can be found like this.

693:3x 3x 7x 11

386:2x 193

934:2x 467

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 2x 3x 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 247344700680/(1x396)

LCM = 247344700680/396

LCM = 624607830

Thus, we can understand that the LCM of 693,386,934,990 is 624607830.
