Given numbers are 2,758,438,243

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

The LCM of 2,758,438,243 is 13446162.

Find LCM of 2,758,438,243 with Prime Factorization

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

2 x 3 x 1 x 379 x 73 x 81 = 13446162

Therefore, the lowest common multiple of 2,758,438,243 is 13446162.

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.

2 x 758 x 438 x 243 = 161353944

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.

2 : 1, 2

758 : 1, 2, 379, 758

438 : 1, 2, 3, 6, 73, 146, 219, 438

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,758,438,243, is 1.

Now, the common factors can be found like this.

2:2

758:2x 379

438:2x 3x 73

243:3x 3x 3x 3x 3

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 161353944/(1x12)

LCM = 161353944/12

LCM = 13446162

Thus, we can understand that the LCM of 2,758,438,243 is 13446162.
