Calculate the LCM of 878,861,410,774

Given numbers are 878,861,410,774

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 878,861,410,774 is 487592910.

Find LCM of 878,861,410,774 with Prime Factorization


2 878, 861, 410, 774
3 439, 861, 205, 387
41 439, 287, 205, 129
439, 7, 5, 129

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

2 x 3 x 41 x 439 x 7 x 5 x 129 = 487592910

Therefore, the lowest common multiple of 878,861,410,774 is 487592910.

LCM Formula to Find Lowest Common Multiple of 878,861,410,774

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.

878 x 861 x 410 x 774 = 239895711720

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.

878 : 1, 2, 439, 878

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

410 : 1, 2, 5, 10, 41, 82, 205, 410

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,861,410,774, is 1.

Now, the common factors can be found like this.

878:2x 439

861:3x 7x 41

410:2x 5x 41

774:2x 3x 3x 43

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 41 = 492

Therefore, the value for common factors is 492.

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 = 239895711720/(1x492)

LCM = 239895711720/492

LCM = 487592910

Thus, we can understand that the LCM of 878,861,410,774 is 487592910.
