Given numbers are 194,432,689,474,561

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

The LCM of 194,432,689,474,561 is 426523928688.

Find LCM of 194,432,689,474,561 with Prime Factorization

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

2 x 3 x 97 x 72 x 689 x 79 x 187 = 426523928688

Therefore, the lowest common multiple of 194,432,689,474,561 is 426523928688.

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 432 x 689 x 474 x 561 = 15354861432768

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

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

689 : 1, 13, 53, 689

474 : 1, 2, 3, 6, 79, 158, 237, 474

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,432,689,474,561, is 1.

Now, the common factors can be found like this.

194:2x 97

432:2x 2x 2x 2x 3x 3x 3

689:13x 53

474:2x 3x 79

561:3x 11x 17

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 15354861432768/(1x36)

LCM = 15354861432768/36

LCM = 426523928688

Thus, we can understand that the LCM of 194,432,689,474,561 is 426523928688.
