The LCM of 768,616,990 is 887040.

Find LCM of 768,616,990 with Prime Factorization


2 768, 616, 990
2 384, 308, 495
2 192, 154, 495
3 96, 77, 495
11 32, 77, 165
32, 7, 15

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

2 x 2 x 2 x 3 x 11 x 32 x 7 x 15 = 887040

Therefore, the lowest common multiple of 768,616,990 is 887040.

LCM Formula to Find Lowest Common Multiple of 768,616,990

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.

768 x 616 x 990 = 468357120

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

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

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,616,990, is 2.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

616:2x 2x 2x 7x 11

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 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 468357120/(2x264)

LCM = 468357120/528

LCM = 887040

Thus, we can understand that the LCM of 768,616,990 is 887040.
