Given numbers are 939,124,912,990

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

The LCM of 939,124,912,990 is 1460107440.

Find LCM of 939,124,912,990 with Prime Factorization

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

2 x 2 x 3 x 313 x 31 x 76 x 165 = 1460107440

Therefore, the lowest common multiple of 939,124,912,990 is 1460107440.

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.

939 x 124 x 912 x 990 = 105127735680

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.

939 : 1, 3, 313, 939

124 : 1, 2, 4, 31, 62, 124

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,124,912,990, is 1.

Now, the common factors can be found like this.

939:3x 313

124:2x 2x 31

912:2x 2x 2x 2x 3x 19

990:2x 3x 3x 5x 11

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

2x 2x 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 105127735680/(1x72)

LCM = 105127735680/72

LCM = 1460107440

Thus, we can understand that the LCM of 939,124,912,990 is 1460107440.
