Calculate the LCM of 842,422,874

Given numbers are 842,422,874

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

The LCM of 842,422,874 is 77638294.

Find LCM of 842,422,874 with Prime Factorization


2 842, 422, 874
421, 211, 437

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

2 x 421 x 211 x 437 = 77638294

Therefore, the lowest common multiple of 842,422,874 is 77638294.

LCM Formula to Find Lowest Common Multiple of 842,422,874

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.

842 x 422 x 874 = 310553176

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.

842 : 1, 2, 421, 842

422 : 1, 2, 211, 422

874 : 1, 2, 19, 23, 38, 46, 437, 874

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,422,874, is 2.

Now, the common factors can be found like this.

842:2x 421

422:2x 211

874:2x 19x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 310553176/(2x2)

LCM = 310553176/4

LCM = 77638294

Thus, we can understand that the LCM of 842,422,874 is 77638294.
