Given numbers are 543,644,478,274,905

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

The LCM of 543,644,478,274,905 is 57249825780.

Find LCM of 543,644,478,274,905 with Prime Factorization

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

2 x 181 x 3 x 322 x 239 x 137 x 5 = 57249825780

Therefore, the lowest common multiple of 543,644,478,274,905 is 57249825780.

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.

543 x 644 x 478 x 274 x 905 = 41448873864720

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.

543 : 1, 3, 181, 543

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

478 : 1, 2, 239, 478

274 : 1, 2, 137, 274

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,644,478,274,905, is 1.

Now, the common factors can be found like this.

543:3x 181

644:2x 2x 7x 23

478:2x 239

274:2x 137

905:5x 181

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 181 = 724

Therefore, the value for common factors is 724.

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 = 41448873864720/(1x724)

LCM = 41448873864720/724

LCM = 57249825780

Thus, we can understand that the LCM of 543,644,478,274,905 is 57249825780.
