LCM Formula to Find Lowest Common Multiple of 861,695,261,480,580

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.

861 x 695 x 261 x 480 x 580 = 43480816848000

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

695 : 1, 5, 139, 695

261 : 1, 3, 9, 29, 87, 261

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,695,261,480,580, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

695:5x 139

261:3x 3x 29

480:2x 2x 2x 2x 2x 3x 5

580:2x 2x 5x 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 3x 3x 5x 5x 29 = 26100

Therefore, the value for common factors is 26100.

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 = 43480816848000/(1x26100)

LCM = 43480816848000/26100

LCM = 1665931680

Thus, we can understand that the LCM of 861,695,261,480,580 is 1665931680.
