Given numbers are 1,242,869,530

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

The LCM of 1,242,869,530 is 5066270.

Find LCM of 1,242,869,530 with Prime Factorization

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

2 x 11 x 1 x 11 x 79 x 265 = 5066270

Therefore, the lowest common multiple of 1,242,869,530 is 5066270.

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 869 x 530 = 111457940

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

869 : 1, 11, 79, 869

530 : 1, 2, 5, 10, 53, 106, 265, 530

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,242,869,530, is 1.

Now, the common factors can be found like this.

1:

242:2x 11x 11

869:11x 79

530:2x 5x 53

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 = 111457940/(1x22)

LCM = 111457940/22

LCM = 5066270

Thus, we can understand that the LCM of 1,242,869,530 is 5066270.
