Given numbers are 641,289,197,641,775

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

The LCM of 641,289,197,641,775 is 28282891075.

Find LCM of 641,289,197,641,775 with Prime Factorization

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

641 x 1 x 289 x 197 x 1 x 775 = 28282891075

Therefore, the lowest common multiple of 641,289,197,641,775 is 28282891075.

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.

641 x 289 x 197 x 641 x 775 = 18129333179075

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.

641 : 1, 641

289 : 1, 17, 289

197 : 1, 197

641 : 1, 641

775 : 1, 5, 25, 31, 155, 775

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,289,197,641,775, is 1.

Now, the common factors can be found like this.

641:641

289:17x 17

197:197

641:641

775:5x 5x 31

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

641 = 641

Therefore, the value for common factors is 641.

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 = 18129333179075/(1x641)

LCM = 18129333179075/641

LCM = 28282891075

Thus, we can understand that the LCM of 641,289,197,641,775 is 28282891075.
