Given numbers are 638,737,122,517

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

The LCM of 638,737,122,517 is 122552782.

Find LCM of 638,737,122,517 with Prime Factorization

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

2 x 11 x 29 x 67 x 61 x 47 = 122552782

Therefore, the lowest common multiple of 638,737,122,517 is 122552782.

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 737 x 122 x 517 = 29657773244

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

737 : 1, 11, 67, 737

122 : 1, 2, 61, 122

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,737,122,517, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

737:11x 67

122:2x 61

517:11x 47

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

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 29657773244/(1x242)

LCM = 29657773244/242

LCM = 122552782

Thus, we can understand that the LCM of 638,737,122,517 is 122552782.
