Given numbers are 890,234,661,449

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

The LCM of 890,234,661,449 is 30904638570.

Find LCM of 890,234,661,449 with Prime Factorization

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

2 x 445 x 117 x 661 x 449 = 30904638570

Therefore, the lowest common multiple of 890,234,661,449 is 30904638570.

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.

890 x 234 x 661 x 449 = 61809277140

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

661 : 1, 661

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,234,661,449, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

234:2x 3x 3x 13

661:661

449:449

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 = 61809277140/(1x2)

LCM = 61809277140/2

LCM = 30904638570

Thus, we can understand that the LCM of 890,234,661,449 is 30904638570.
