Given numbers are 561,212,573,657

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

The LCM of 561,212,573,657 is 4974806628.

Find LCM of 561,212,573,657 with Prime Factorization

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

3 x 187 x 212 x 191 x 219 = 4974806628

Therefore, the lowest common multiple of 561,212,573,657 is 4974806628.

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.

561 x 212 x 573 x 657 = 44773259652

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.

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

212 : 1, 2, 4, 53, 106, 212

573 : 1, 3, 191, 573

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,212,573,657, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

212:2x 2x 53

573:3x 191

657:3x 3x 73

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 44773259652/(1x9)

LCM = 44773259652/9

LCM = 4974806628

Thus, we can understand that the LCM of 561,212,573,657 is 4974806628.
