Given numbers are 194,642,535,821

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

The LCM of 194,642,535,821 is 255634770.

Find LCM of 194,642,535,821 with Prime Factorization

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

2 x 107 x 97 x 3 x 5 x 821 = 255634770

Therefore, the lowest common multiple of 194,642,535,821 is 255634770.

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.

194 x 642 x 535 x 821 = 54705840780

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.

194 : 1, 2, 97, 194

642 : 1, 2, 3, 6, 107, 214, 321, 642

535 : 1, 5, 107, 535

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,642,535,821, is 1.

Now, the common factors can be found like this.

194:2x 97

642:2x 3x 107

535:5x 107

821:821

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 54705840780/(1x214)

LCM = 54705840780/214

LCM = 255634770

Thus, we can understand that the LCM of 194,642,535,821 is 255634770.
