Given numbers are 635,780,227,181,665

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

The LCM of 635,780,227,181,665 is 541320403260.

Find LCM of 635,780,227,181,665 with Prime Factorization

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

5 x 127 x 156 x 227 x 181 x 133 = 541320403260

Therefore, the lowest common multiple of 635,780,227,181,665 is 541320403260.

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.

635 x 780 x 227 x 181 x 665 = 13533010081500

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.

635 : 1, 5, 127, 635

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

227 : 1, 227

181 : 1, 181

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 635,780,227,181,665, is 1.

Now, the common factors can be found like this.

635:5x 127

780:2x 2x 3x 5x 13

227:227

181:181

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.

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 13533010081500/(1x25)

LCM = 13533010081500/25

LCM = 541320403260

Thus, we can understand that the LCM of 635,780,227,181,665 is 541320403260.
