Given numbers are 196,691,221,460

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

The LCM of 196,691,221,460 is 3442105940.

Find LCM of 196,691,221,460 with Prime Factorization

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

2 x 2 x 49 x 691 x 221 x 115 = 3442105940

Therefore, the lowest common multiple of 196,691,221,460 is 3442105940.

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.

196 x 691 x 221 x 460 = 13768423760

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.

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

691 : 1, 691

221 : 1, 13, 17, 221

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,691,221,460, is 1.

Now, the common factors can be found like this.

196:2x 2x 7x 7

691:691

221:13x 17

460:2x 2x 5x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 13768423760/(1x4)

LCM = 13768423760/4

LCM = 3442105940

Thus, we can understand that the LCM of 196,691,221,460 is 3442105940.
