Given numbers are 331,991,508,742

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

The LCM of 331,991,508,742 is 61821461828.

Find LCM of 331,991,508,742 with Prime Factorization

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

2 x 331 x 991 x 254 x 371 = 61821461828

Therefore, the lowest common multiple of 331,991,508,742 is 61821461828.

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 991 x 508 x 742 = 123642923656

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

991 : 1, 991

508 : 1, 2, 4, 127, 254, 508

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,991,508,742, is 1.

Now, the common factors can be found like this.

331:331

991:991

508:2x 2x 127

742:2x 7x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 123642923656/(1x2)

LCM = 123642923656/2

LCM = 61821461828

Thus, we can understand that the LCM of 331,991,508,742 is 61821461828.
