Given numbers are 939,912,898,420

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

The LCM of 939,912,898,420 is 4485941040.

Find LCM of 939,912,898,420 with Prime Factorization

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

2 x 2 x 3 x 313 x 76 x 449 x 35 = 4485941040

Therefore, the lowest common multiple of 939,912,898,420 is 4485941040.

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 912 x 898 x 420 = 322987754880

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

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

898 : 1, 2, 449, 898

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,912,898,420, is 1.

Now, the common factors can be found like this.

939:3x 313

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

898:2x 449

420:2x 2x 3x 5x 7

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 = 322987754880/(1x72)

LCM = 322987754880/72

LCM = 4485941040

Thus, we can understand that the LCM of 939,912,898,420 is 4485941040.
