Given numbers are 521,135,521,761

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

The LCM of 521,135,521,761 is 53524935.

Find LCM of 521,135,521,761 with Prime Factorization

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

521 x 1 x 135 x 1 x 761 = 53524935

Therefore, the lowest common multiple of 521,135,521,761 is 53524935.

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.

521 x 135 x 521 x 761 = 27886491135

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.

521 : 1, 521

135 : 1, 3, 5, 9, 15, 27, 45, 135

521 : 1, 521

761 : 1, 761

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,135,521,761, is 1.

Now, the common factors can be found like this.

521:521

135:3x 3x 3x 5

521:521

761:761

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

521 = 521

Therefore, the value for common factors is 521.

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 = 27886491135/(1x521)

LCM = 27886491135/521

LCM = 53524935

Thus, we can understand that the LCM of 521,135,521,761 is 53524935.
