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

2 x 2 x 2 x 2 x 2 x 2 x 5 x 1 x 269 x 2 x 377 = 64904320

Therefore, the lowest common multiple of 320,538,640,754 is 64904320.

LCM Formula to Find Lowest Common Multiple of 320,538,640,754

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.

320 x 538 x 640 x 754 = 83077529600

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.

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

538 : 1, 2, 269, 538

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

754 : 1, 2, 13, 26, 29, 58, 377, 754

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,538,640,754, is 2.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

538:2x 269

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

754:2x 13x 29

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 2x 5 = 640

Therefore, the value for common factors is 640.

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 = 83077529600/(2x640)

LCM = 83077529600/1280

LCM = 64904320

Thus, we can understand that the LCM of 320,538,640,754 is 64904320.
