Given numbers are 813,749,481,128,938

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

The LCM of 813,749,481,128,938 is 2511899225472.

Find LCM of 813,749,481,128,938 with Prime Factorization

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

2 x 7 x 813 x 107 x 481 x 64 x 67 = 2511899225472

Therefore, the lowest common multiple of 813,749,481,128,938 is 2511899225472.

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.

813 x 749 x 481 x 128 x 938 = 35166589156608

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.

813 : 1, 3, 271, 813

749 : 1, 7, 107, 749

481 : 1, 13, 37, 481

128 : 1, 2, 4, 8, 16, 32, 64, 128

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,749,481,128,938, is 1.

Now, the common factors can be found like this.

813:3x 271

749:7x 107

481:13x 37

128:2x 2x 2x 2x 2x 2x 2

938:2x 7x 67

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 35166589156608/(1x14)

LCM = 35166589156608/14

LCM = 2511899225472

Thus, we can understand that the LCM of 813,749,481,128,938 is 2511899225472.
