Given numbers are 638,313,178,737

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

The LCM of 638,313,178,737 is 1190775322.

Find LCM of 638,313,178,737 with Prime Factorization

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

2 x 11 x 29 x 313 x 89 x 67 = 1190775322

Therefore, the lowest common multiple of 638,313,178,737 is 1190775322.

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.

638 x 313 x 178 x 737 = 26197057084

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

313 : 1, 313

178 : 1, 2, 89, 178

737 : 1, 11, 67, 737

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,313,178,737, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

313:313

178:2x 89

737:11x 67

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 26197057084/(1x22)

LCM = 26197057084/22

LCM = 1190775322

Thus, we can understand that the LCM of 638,313,178,737 is 1190775322.
