Given numbers are 695,218,921,981

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

The LCM of 695,218,921,981 is 418622130.

Find LCM of 695,218,921,981 with Prime Factorization

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

3 x 109 x 695 x 2 x 307 x 3 = 418622130

Therefore, the lowest common multiple of 695,218,921,981 is 418622130.

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.

695 x 218 x 921 x 981 = 136889436510

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.

695 : 1, 5, 139, 695

218 : 1, 2, 109, 218

921 : 1, 3, 307, 921

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,218,921,981, is 1.

Now, the common factors can be found like this.

695:5x 139

218:2x 109

921:3x 307

981:3x 3x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 136889436510/(1x327)

LCM = 136889436510/327

LCM = 418622130

Thus, we can understand that the LCM of 695,218,921,981 is 418622130.
