LCM Formula to Find Lowest Common Multiple of 768,640,437,401

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 640 x 437 x 401 = 86132490240

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

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

437 : 1, 19, 23, 437

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,640,437,401, is 1.

Now, the common factors can be found like this.

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

640:2x 2x 2x 2x 2x 2x 2x 5

437:19x 23

401:401

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 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 86132490240/(1x128)

LCM = 86132490240/128

LCM = 672910080

Thus, we can understand that the LCM of 768,640,437,401 is 672910080.
