Given numbers are 193,421,610,428

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

The LCM of 193,421,610,428 is 10606766620.

Find LCM of 193,421,610,428 with Prime Factorization

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

2 x 193 x 421 x 305 x 214 = 10606766620

Therefore, the lowest common multiple of 193,421,610,428 is 10606766620.

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 421 x 610 x 428 = 21213533240

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

421 : 1, 421

610 : 1, 2, 5, 10, 61, 122, 305, 610

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,421,610,428, is 1.

Now, the common factors can be found like this.

193:193

421:421

610:2x 5x 61

428:2x 2x 107

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

2 = 2

Therefore, the value for common factors is 2.

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 = 21213533240/(1x2)

LCM = 21213533240/2

LCM = 10606766620

Thus, we can understand that the LCM of 193,421,610,428 is 10606766620.
