Given numbers are 561,642,284,227

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

The LCM of 561,642,284,227 is 3869820636.

Find LCM of 561,642,284,227 with Prime Factorization

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

2 x 3 x 187 x 107 x 142 x 227 = 3869820636

Therefore, the lowest common multiple of 561,642,284,227 is 3869820636.

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 642 x 284 x 227 = 23218923816

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

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

284 : 1, 2, 4, 71, 142, 284

227 : 1, 227

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,642,284,227, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

642:2x 3x 107

284:2x 2x 71

227:227

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 23218923816/(1x6)

LCM = 23218923816/6

LCM = 3869820636

Thus, we can understand that the LCM of 561,642,284,227 is 3869820636.
