LCM Formula to Find Lowest Common Multiple of 640,639,329,640,587

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.

640 x 639 x 329 x 640 x 587 = 50546932531200

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.

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

639 : 1, 3, 9, 71, 213, 639

329 : 1, 7, 47, 329

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

587 : 1, 587

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,639,329,640,587, is 1.

Now, the common factors can be found like this.

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

639:3x 3x 71

329:7x 47

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

587:587

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 = 50546932531200/(1x640)

LCM = 50546932531200/640

LCM = 78979582080

Thus, we can understand that the LCM of 640,639,329,640,587 is 78979582080.
