Given numbers are 668,461,121,178,809

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

The LCM of 668,461,121,178,809 is 2682880237708.

Find LCM of 668,461,121,178,809 with Prime Factorization

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

2 x 334 x 461 x 121 x 89 x 809 = 2682880237708

Therefore, the lowest common multiple of 668,461,121,178,809 is 2682880237708.

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.

668 x 461 x 121 x 178 x 809 = 5365760475416

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.

668 : 1, 2, 4, 167, 334, 668

461 : 1, 461

121 : 1, 11, 121

178 : 1, 2, 89, 178

809 : 1, 809

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,461,121,178,809, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

461:461

121:11x 11

178:2x 89

809:809

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 = 5365760475416/(1x2)

LCM = 5365760475416/2

LCM = 2682880237708

Thus, we can understand that the LCM of 668,461,121,178,809 is 2682880237708.
