Calculate the LCM of 988,872,256,176

Given numbers are 988,872,256,176

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

The LCM of 988,872,256,176 is 75815168.

Find LCM of 988,872,256,176 with Prime Factorization


2 988, 872, 256, 176
2 494, 436, 128, 88
2 247, 218, 64, 44
2 247, 109, 32, 22
247, 109, 16, 11

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

2 x 2 x 2 x 2 x 247 x 109 x 16 x 11 = 75815168

Therefore, the lowest common multiple of 988,872,256,176 is 75815168.

LCM Formula to Find Lowest Common Multiple of 988,872,256,176

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.

988 x 872 x 256 x 176 = 38817366016

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

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

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,872,256,176, is 4.

Now, the common factors can be found like this.

988:2x 2x 13x 19

872:2x 2x 2x 109

256:2x 2x 2x 2x 2x 2x 2x 2

176:2x 2x 2x 2x 11

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 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 38817366016/(4x128)

LCM = 38817366016/512

LCM = 75815168

Thus, we can understand that the LCM of 988,872,256,176 is 75815168.
