Given numbers are 503,217,821,987

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

The LCM of 503,217,821,987 is 12635428911.

Find LCM of 503,217,821,987 with Prime Factorization

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

7 x 503 x 31 x 821 x 141 = 12635428911

Therefore, the lowest common multiple of 503,217,821,987 is 12635428911.

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.

503 x 217 x 821 x 987 = 88448002377

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.

503 : 1, 503

217 : 1, 7, 31, 217

821 : 1, 821

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 503,217,821,987, is 1.

Now, the common factors can be found like this.

503:503

217:7x 31

821:821

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.

7 = 7

Therefore, the value for common factors is 7.

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 = 88448002377/(1x7)

LCM = 88448002377/7

LCM = 12635428911

Thus, we can understand that the LCM of 503,217,821,987 is 12635428911.
