Calculate the LCM of 181,862,862,762,631

Given numbers are 181,862,862,762,631

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

The LCM of 181,862,862,762,631 is 37509405042.

Find LCM of 181,862,862,762,631 with Prime Factorization


2 181, 862, 862, 762, 631
431 181, 431, 431, 381, 631
181, 1, 1, 381, 631

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

2 x 431 x 181 x 1 x 1 x 381 x 631 = 37509405042

Therefore, the lowest common multiple of 181,862,862,762,631 is 37509405042.

LCM Formula to Find Lowest Common Multiple of 181,862,862,762,631

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.

181 x 862 x 862 x 762 x 631 = 64666214292408

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.

181 : 1, 181

862 : 1, 2, 431, 862

862 : 1, 2, 431, 862

762 : 1, 2, 3, 6, 127, 254, 381, 762

631 : 1, 631

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,862,862,762,631, is 1.

Now, the common factors can be found like this.

181:181

862:2x 431

862:2x 431

762:2x 3x 127

631:631

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 431 = 1724

Therefore, the value for common factors is 1724.

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 = 64666214292408/(1x1724)

LCM = 64666214292408/1724

LCM = 37509405042

Thus, we can understand that the LCM of 181,862,862,762,631 is 37509405042.
