Given numbers are 221,905,533,728

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

The LCM of 221,905,533,728 is 459211480.

Find LCM of 221,905,533,728 with Prime Factorization

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

13 x 17 x 905 x 41 x 56 = 459211480

Therefore, the lowest common multiple of 221,905,533,728 is 459211480.

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.

221 x 905 x 533 x 728 = 77606740120

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.

221 : 1, 13, 17, 221

905 : 1, 5, 181, 905

533 : 1, 13, 41, 533

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,905,533,728, is 1.

Now, the common factors can be found like this.

221:13x 17

905:5x 181

533:13x 41

728:2x 2x 2x 7x 13

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 = 77606740120/(1x169)

LCM = 77606740120/169

LCM = 459211480

Thus, we can understand that the LCM of 221,905,533,728 is 459211480.
