Given numbers are 217,987,209

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

The LCM of 217,987,209 is 6394773.

Find LCM of 217,987,209 with Prime Factorization

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

7 x 31 x 141 x 209 = 6394773

Therefore, the lowest common multiple of 217,987,209 is 6394773.

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.

217 x 987 x 209 = 44763411

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.

217 : 1, 7, 31, 217

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

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,987,209, is 1.

Now, the common factors can be found like this.

217:7x 31

987:3x 7x 47

209:11x 19

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 = 44763411/(1x7)

LCM = 44763411/7

LCM = 6394773

Thus, we can understand that the LCM of 217,987,209 is 6394773.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 748, 587, 283
• LCM of 271, 714, 124
