Given numbers are 658,698,221,194

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

The LCM of 658,698,221,194 is 4922835554.

Find LCM of 658,698,221,194 with Prime Factorization

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

2 x 329 x 349 x 221 x 97 = 4922835554

Therefore, the lowest common multiple of 658,698,221,194 is 4922835554.

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.

658 x 698 x 221 x 194 = 19691342216

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

698 : 1, 2, 349, 698

221 : 1, 13, 17, 221

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,698,221,194, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

698:2x 349

221:13x 17

194:2x 97

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 = 19691342216/(1x4)

LCM = 19691342216/4

LCM = 4922835554

Thus, we can understand that the LCM of 658,698,221,194 is 4922835554.
