Calculate the LCM of 872,878,515,824

Given numbers are 872,878,515,824

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

The LCM of 872,878,515,824 is 197146120.

Find LCM of 872,878,515,824 with Prime Factorization


2 872, 878, 515, 824
2 436, 439, 515, 412
2 218, 439, 515, 206
103 109, 439, 515, 103
109, 439, 5, 1

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

2 x 2 x 2 x 103 x 109 x 439 x 5 x 1 = 197146120

Therefore, the lowest common multiple of 872,878,515,824 is 197146120.

LCM Formula to Find Lowest Common Multiple of 872,878,515,824

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.

872 x 878 x 515 x 824 = 324896805760

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

878 : 1, 2, 439, 878

515 : 1, 5, 103, 515

824 : 1, 2, 4, 8, 103, 206, 412, 824

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,878,515,824, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

878:2x 439

515:5x 103

824:2x 2x 2x 103

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 2x 2x 103 = 1648

Therefore, the value for common factors is 1648.

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 = 324896805760/(1x1648)

LCM = 324896805760/1648

LCM = 197146120

Thus, we can understand that the LCM of 872,878,515,824 is 197146120.
