Given numbers are 331,365,991,690

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

The LCM of 331,365,991,690 is 16522417770.

Find LCM of 331,365,991,690 with Prime Factorization

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

5 x 331 x 73 x 991 x 138 = 16522417770

Therefore, the lowest common multiple of 331,365,991,690 is 16522417770.

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.

331 x 365 x 991 x 690 = 82612088850

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.

331 : 1, 331

365 : 1, 5, 73, 365

991 : 1, 991

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,365,991,690, is 1.

Now, the common factors can be found like this.

331:331

365:5x 73

991:991

690:2x 3x 5x 23

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

5 = 5

Therefore, the value for common factors is 5.

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 = 82612088850/(1x5)

LCM = 82612088850/5

LCM = 16522417770

Thus, we can understand that the LCM of 331,365,991,690 is 16522417770.
