Given numbers are 445,693,133,646

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

The LCM of 445,693,133,646 is 199216710.

Find LCM of 445,693,133,646 with Prime Factorization

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

7 x 19 x 445 x 99 x 1 x 34 = 199216710

Therefore, the lowest common multiple of 445,693,133,646 is 199216710.

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.

445 x 693 x 133 x 646 = 26495822430

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.

445 : 1, 5, 89, 445

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

133 : 1, 7, 19, 133

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,693,133,646, is 1.

Now, the common factors can be found like this.

445:5x 89

693:3x 3x 7x 11

133:7x 19

646:2x 17x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 26495822430/(1x133)

LCM = 26495822430/133

LCM = 199216710

Thus, we can understand that the LCM of 445,693,133,646 is 199216710.
