Given numbers are 193,660,421,421

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

The LCM of 193,660,421,421 is 53626980.

Find LCM of 193,660,421,421 with Prime Factorization

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

421 x 193 x 660 x 1 x 1 = 53626980

Therefore, the lowest common multiple of 193,660,421,421 is 53626980.

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.

193 x 660 x 421 x 421 = 22576958580

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.

193 : 1, 193

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

421 : 1, 421

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,660,421,421, is 1.

Now, the common factors can be found like this.

193:193

660:2x 2x 3x 5x 11

421:421

421:421

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

421 = 421

Therefore, the value for common factors is 421.

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 = 22576958580/(1x421)

LCM = 22576958580/421

LCM = 53626980

Thus, we can understand that the LCM of 193,660,421,421 is 53626980.
