Given numbers are 690,807,198,211

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

The LCM of 690,807,198,211 is 1292402430.

Find LCM of 690,807,198,211 with Prime Factorization

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

2 x 3 x 115 x 269 x 33 x 211 = 1292402430

Therefore, the lowest common multiple of 690,807,198,211 is 1292402430.

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.

690 x 807 x 198 x 211 = 23263243740

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

807 : 1, 3, 269, 807

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

211 : 1, 211

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,807,198,211, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

807:3x 269

198:2x 3x 3x 11

211:211

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 23263243740/(1x18)

LCM = 23263243740/18

LCM = 1292402430

Thus, we can understand that the LCM of 690,807,198,211 is 1292402430.
