Given numbers are 543,377,520,221

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

The LCM of 543,377,520,221 is 139203480.

Find LCM of 543,377,520,221 with Prime Factorization

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

13 x 543 x 29 x 40 x 17 = 139203480

Therefore, the lowest common multiple of 543,377,520,221 is 139203480.

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 377 x 520 x 221 = 23525388120

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

377 : 1, 13, 29, 377

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,377,520,221, is 1.

Now, the common factors can be found like this.

543:3x 181

377:13x 29

520:2x 2x 2x 5x 13

221:13x 17

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 23525388120/(1x169)

LCM = 23525388120/169

LCM = 139203480

Thus, we can understand that the LCM of 543,377,520,221 is 139203480.
