Given numbers are 661,722,183,638

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

The LCM of 661,722,183,638 is 27859956234.

Find LCM of 661,722,183,638 with Prime Factorization

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

2 x 661 x 361 x 183 x 319 = 27859956234

Therefore, the lowest common multiple of 661,722,183,638 is 27859956234.

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.

661 x 722 x 183 x 638 = 55719912468

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.

661 : 1, 661

722 : 1, 2, 19, 38, 361, 722

183 : 1, 3, 61, 183

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,722,183,638, is 1.

Now, the common factors can be found like this.

661:661

722:2x 19x 19

183:3x 61

638:2x 11x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 55719912468/(1x2)

LCM = 55719912468/2

LCM = 27859956234

Thus, we can understand that the LCM of 661,722,183,638 is 27859956234.
