Given numbers are 153,642,230,424,661

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

The LCM of 153,642,230,424,661 is 527643223560.

Find LCM of 153,642,230,424,661 with Prime Factorization

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

2 x 3 x 51 x 107 x 115 x 212 x 661 = 527643223560

Therefore, the lowest common multiple of 153,642,230,424,661 is 527643223560.

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.

153 x 642 x 230 x 424 x 661 = 6331718682720

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.

153 : 1, 3, 9, 17, 51, 153

642 : 1, 2, 3, 6, 107, 214, 321, 642

230 : 1, 2, 5, 10, 23, 46, 115, 230

424 : 1, 2, 4, 8, 53, 106, 212, 424

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,642,230,424,661, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

642:2x 3x 107

230:2x 5x 23

424:2x 2x 2x 53

661:661

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 6331718682720/(1x12)

LCM = 6331718682720/12

LCM = 527643223560

Thus, we can understand that the LCM of 153,642,230,424,661 is 527643223560.
