Given numbers are 997,858,221,635

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

The LCM of 997,858,221,635 is 9234323670.

Find LCM of 997,858,221,635 with Prime Factorization

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

13 x 997 x 66 x 17 x 635 = 9234323670

Therefore, the lowest common multiple of 997,858,221,635 is 9234323670.

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.

997 x 858 x 221 x 635 = 120046207710

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.

997 : 1, 997

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

221 : 1, 13, 17, 221

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,858,221,635, is 1.

Now, the common factors can be found like this.

997:997

858:2x 3x 11x 13

221:13x 17

635:5x 127

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

13 = 13

Therefore, the value for common factors is 13.

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 = 120046207710/(1x13)

LCM = 120046207710/13

LCM = 9234323670

Thus, we can understand that the LCM of 997,858,221,635 is 9234323670.
