Given numbers are 908,481,420,121

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

The LCM of 908,481,420,121 is 5548883340.

Find LCM of 908,481,420,121 with Prime Factorization

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

2 x 2 x 227 x 481 x 105 x 121 = 5548883340

Therefore, the lowest common multiple of 908,481,420,121 is 5548883340.

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.

908 x 481 x 420 x 121 = 22195533360

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.

908 : 1, 2, 4, 227, 454, 908

481 : 1, 13, 37, 481

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

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,481,420,121, is 1.

Now, the common factors can be found like this.

908:2x 2x 227

481:13x 37

420:2x 2x 3x 5x 7

121:11x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 22195533360/(1x4)

LCM = 22195533360/4

LCM = 5548883340

Thus, we can understand that the LCM of 908,481,420,121 is 5548883340.
