LCM Formula to Find Lowest Common Multiple of 858,939,520,397

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.

858 x 939 x 520 x 397 = 166320863280

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

939 : 1, 3, 313, 939

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,939,520,397, is 1.

Now, the common factors can be found like this.

858:2x 3x 11x 13

939:3x 313

520:2x 2x 2x 5x 13

397:397

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 13 = 78

Therefore, the value for common factors is 78.

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 = 166320863280/(1x78)

LCM = 166320863280/78

LCM = 2132318760

Thus, we can understand that the LCM of 858,939,520,397 is 2132318760.
