Given numbers are 451,615,121,521

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

The LCM of 451,615,121,521 is 38770215.

Find LCM of 451,615,121,521 with Prime Factorization

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

11 x 41 x 1 x 15 x 11 x 521 = 38770215

Therefore, the lowest common multiple of 451,615,121,521 is 38770215.

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.

451 x 615 x 121 x 521 = 17485366965

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.

451 : 1, 11, 41, 451

615 : 1, 3, 5, 15, 41, 123, 205, 615

121 : 1, 11, 121

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,615,121,521, is 1.

Now, the common factors can be found like this.

451:11x 41

615:3x 5x 41

121:11x 11

521:521

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

11x 41 = 451

Therefore, the value for common factors is 451.

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 = 17485366965/(1x451)

LCM = 17485366965/451

LCM = 38770215

Thus, we can understand that the LCM of 451,615,121,521 is 38770215.
