Given numbers are 693,578,605,821

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

The LCM of 693,578,605,821 is 18087015870.

Find LCM of 693,578,605,821 with Prime Factorization

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

11 x 63 x 578 x 55 x 821 = 18087015870

Therefore, the lowest common multiple of 693,578,605,821 is 18087015870.

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.

693 x 578 x 605 x 821 = 198957174570

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.

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

578 : 1, 2, 17, 34, 289, 578

605 : 1, 5, 11, 55, 121, 605

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,578,605,821, is 1.

Now, the common factors can be found like this.

693:3x 3x 7x 11

578:2x 17x 17

605:5x 11x 11

821:821

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

11 = 11

Therefore, the value for common factors is 11.

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 = 198957174570/(1x11)

LCM = 198957174570/11

LCM = 18087015870

Thus, we can understand that the LCM of 693,578,605,821 is 18087015870.
