Given numbers are 843,721,720,477

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

The LCM of 843,721,720,477 is 7731254160.

Find LCM of 843,721,720,477 with Prime Factorization

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

3 x 3 x 281 x 721 x 80 x 53 = 7731254160

Therefore, the lowest common multiple of 843,721,720,477 is 7731254160.

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.

843 x 721 x 720 x 477 = 208743862320

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.

843 : 1, 3, 281, 843

721 : 1, 7, 103, 721

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

477 : 1, 3, 9, 53, 159, 477

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,721,720,477, is 1.

Now, the common factors can be found like this.

843:3x 281

721:7x 103

720:2x 2x 2x 2x 3x 3x 5

477:3x 3x 53

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 208743862320/(1x27)

LCM = 208743862320/27

LCM = 7731254160

Thus, we can understand that the LCM of 843,721,720,477 is 7731254160.
