Given numbers are 497,195,361,987

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

The LCM of 497,195,361,987 is 1644356805.

Find LCM of 497,195,361,987 with Prime Factorization

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

3 x 7 x 71 x 65 x 361 x 47 = 1644356805

Therefore, the lowest common multiple of 497,195,361,987 is 1644356805.

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.

497 x 195 x 361 x 987 = 34531492905

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.

497 : 1, 7, 71, 497

195 : 1, 3, 5, 13, 15, 39, 65, 195

361 : 1, 19, 361

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,195,361,987, is 1.

Now, the common factors can be found like this.

497:7x 71

195:3x 5x 13

361:19x 19

987:3x 7x 47

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 34531492905/(1x21)

LCM = 34531492905/21

LCM = 1644356805

Thus, we can understand that the LCM of 497,195,361,987 is 1644356805.
