LCM Formula to Find Lowest Common Multiple of 396,820,615,961

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.

396 x 820 x 615 x 961 = 191914390800

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.

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

615 : 1, 3, 5, 15, 41, 123, 205, 615

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,820,615,961, is 1.

Now, the common factors can be found like this.

396:2x 2x 3x 3x 11

820:2x 2x 5x 41

615:3x 5x 41

961:31x 31

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 5x 41 = 2460

Therefore, the value for common factors is 2460.

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 = 191914390800/(1x2460)

LCM = 191914390800/2460

LCM = 78013980

Thus, we can understand that the LCM of 396,820,615,961 is 78013980.
