Given numbers are 122,772,838,389

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

The LCM of 122,772,838,389 is 7675572172.

Find LCM of 122,772,838,389 with Prime Factorization

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

2 x 61 x 386 x 419 x 389 = 7675572172

Therefore, the lowest common multiple of 122,772,838,389 is 7675572172.

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.

122 x 772 x 838 x 389 = 30702288688

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.

122 : 1, 2, 61, 122

772 : 1, 2, 4, 193, 386, 772

838 : 1, 2, 419, 838

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,772,838,389, is 1.

Now, the common factors can be found like this.

122:2x 61

772:2x 2x 193

838:2x 419

389:389

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30702288688/(1x4)

LCM = 30702288688/4

LCM = 7675572172

Thus, we can understand that the LCM of 122,772,838,389 is 7675572172.
