Given numbers are 123,351,578,664,661

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

The LCM of 123,351,578,664,661 is 1825401297096.

Find LCM of 123,351,578,664,661 with Prime Factorization

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

2 x 3 x 41 x 117 x 289 x 332 x 661 = 1825401297096

Therefore, the lowest common multiple of 123,351,578,664,661 is 1825401297096.

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.

123 x 351 x 578 x 664 x 661 = 10952407782576

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.

123 : 1, 3, 41, 123

351 : 1, 3, 9, 13, 27, 39, 117, 351

578 : 1, 2, 17, 34, 289, 578

664 : 1, 2, 4, 8, 83, 166, 332, 664

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,351,578,664,661, is 1.

Now, the common factors can be found like this.

123:3x 41

351:3x 3x 3x 13

578:2x 17x 17

664:2x 2x 2x 83

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 3 = 6

Therefore, the value for common factors is 6.

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 = 10952407782576/(1x6)

LCM = 10952407782576/6

LCM = 1825401297096

Thus, we can understand that the LCM of 123,351,578,664,661 is 1825401297096.
