Given numbers are 243,628,785,443

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

The LCM of 243,628,785,443 is 338017860.

Find LCM of 243,628,785,443 with Prime Factorization

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

157 x 243 x 4 x 5 x 443 = 338017860

Therefore, the lowest common multiple of 243,628,785,443 is 338017860.

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.

243 x 628 x 785 x 443 = 53068804020

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.

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

628 : 1, 2, 4, 157, 314, 628

785 : 1, 5, 157, 785

443 : 1, 443

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,628,785,443, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

628:2x 2x 157

785:5x 157

443:443

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

157 = 157

Therefore, the value for common factors is 157.

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 = 53068804020/(1x157)

LCM = 53068804020/157

LCM = 338017860

Thus, we can understand that the LCM of 243,628,785,443 is 338017860.
