Given numbers are 609,121,621,219

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

The LCM of 609,121,621,219 is 1113514479.

Find LCM of 609,121,621,219 with Prime Factorization

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

3 x 203 x 121 x 207 x 73 = 1113514479

Therefore, the lowest common multiple of 609,121,621,219 is 1113514479.

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.

609 x 121 x 621 x 219 = 10021630311

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

121 : 1, 11, 121

621 : 1, 3, 9, 23, 27, 69, 207, 621

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,121,621,219, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

121:11x 11

621:3x 3x 3x 23

219:3x 73

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 10021630311/(1x9)

LCM = 10021630311/9

LCM = 1113514479

Thus, we can understand that the LCM of 609,121,621,219 is 1113514479.
