Given numbers are 931,903,991,991

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

The LCM of 931,903,991,991 is 119018109.

Find LCM of 931,903,991,991 with Prime Factorization

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

7 x 991 x 133 x 129 x 1 x 1 = 119018109

Therefore, the lowest common multiple of 931,903,991,991 is 119018109.

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.

931 x 903 x 991 x 991 = 825628622133

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.

931 : 1, 7, 19, 49, 133, 931

903 : 1, 3, 7, 21, 43, 129, 301, 903

991 : 1, 991

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,903,991,991, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

903:3x 7x 43

991:991

991:991

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

7x 991 = 6937

Therefore, the value for common factors is 6937.

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 = 825628622133/(1x6937)

LCM = 825628622133/6937

LCM = 119018109

Thus, we can understand that the LCM of 931,903,991,991 is 119018109.
