Given numbers are 661,205,369,478

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

The LCM of 661,205,369,478 is 582942510.

Find LCM of 661,205,369,478 with Prime Factorization

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

41 x 661 x 5 x 9 x 478 = 582942510

Therefore, the lowest common multiple of 661,205,369,478 is 582942510.

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 205 x 369 x 478 = 23900642910

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

205 : 1, 5, 41, 205

369 : 1, 3, 9, 41, 123, 369

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,205,369,478, is 1.

Now, the common factors can be found like this.

661:661

205:5x 41

369:3x 3x 41

478:2x 239

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

41 = 41

Therefore, the value for common factors is 41.

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 = 23900642910/(1x41)

LCM = 23900642910/41

LCM = 582942510

Thus, we can understand that the LCM of 661,205,369,478 is 582942510.
