Given numbers are 439,138,678,670

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

The LCM of 439,138,678,670 is 2293331610.

Find LCM of 439,138,678,670 with Prime Factorization

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

2 x 3 x 439 x 23 x 113 x 335 = 2293331610

Therefore, the lowest common multiple of 439,138,678,670 is 2293331610.

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.

439 x 138 x 678 x 670 = 27519979320

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.

439 : 1, 439

138 : 1, 2, 3, 6, 23, 46, 69, 138

678 : 1, 2, 3, 6, 113, 226, 339, 678

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,138,678,670, is 1.

Now, the common factors can be found like this.

439:439

138:2x 3x 23

678:2x 3x 113

670:2x 5x 67

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 = 27519979320/(1x12)

LCM = 27519979320/12

LCM = 2293331610

Thus, we can understand that the LCM of 439,138,678,670 is 2293331610.
