Given numbers are 1,242,122,931

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

The LCM of 1,242,122,931 is 13743422.

Find LCM of 1,242,122,931 with Prime Factorization

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

2 x 1 x 121 x 61 x 931 = 13743422

Therefore, the lowest common multiple of 1,242,122,931 is 13743422.

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.

1 x 242 x 122 x 931 = 27486844

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.

1 : 1

242 : 1, 2, 11, 22, 121, 242

122 : 1, 2, 61, 122

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,242,122,931, is 1.

Now, the common factors can be found like this.

1:

242:2x 11x 11

122:2x 61

931:7x 7x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 27486844/(1x2)

LCM = 27486844/2

LCM = 13743422

Thus, we can understand that the LCM of 1,242,122,931 is 13743422.
