Given numbers are 491,678,226,665

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

The LCM of 491,678,226,665 is 221377170.

Find LCM of 491,678,226,665 with Prime Factorization

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

2 x 113 x 491 x 3 x 1 x 665 = 221377170

Therefore, the lowest common multiple of 491,678,226,665 is 221377170.

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.

491 x 678 x 226 x 665 = 50031240420

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.

491 : 1, 491

678 : 1, 2, 3, 6, 113, 226, 339, 678

226 : 1, 2, 113, 226

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,678,226,665, is 1.

Now, the common factors can be found like this.

491:491

678:2x 3x 113

226:2x 113

665:5x 7x 19

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

2x 113 = 226

Therefore, the value for common factors is 226.

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 = 50031240420/(1x226)

LCM = 50031240420/226

LCM = 221377170

Thus, we can understand that the LCM of 491,678,226,665 is 221377170.
