Given numbers are 192,194,960,221

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

The LCM of 192,194,960,221 is 20579520.

Find LCM of 192,194,960,221 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 3 x 1 x 97 x 5 x 221 = 20579520

Therefore, the lowest common multiple of 192,194,960,221 is 20579520.

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.

192 x 194 x 960 x 221 = 7902535680

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.

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

194 : 1, 2, 97, 194

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,194,960,221, is 1.

Now, the common factors can be found like this.

192:2x 2x 2x 2x 2x 2x 3

194:2x 97

960:2x 2x 2x 2x 2x 2x 3x 5

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.

2x 2x 2x 2x 2x 2x 2x 3 = 384

Therefore, the value for common factors is 384.

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 = 7902535680/(1x384)

LCM = 7902535680/384

LCM = 20579520

Thus, we can understand that the LCM of 192,194,960,221 is 20579520.
