Given numbers are 211,420,242,988

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

The LCM of 211,420,242,988 is 2648585940.

Find LCM of 211,420,242,988 with Prime Factorization

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

2 x 2 x 211 x 105 x 121 x 247 = 2648585940

Therefore, the lowest common multiple of 211,420,242,988 is 2648585940.

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.

211 x 420 x 242 x 988 = 21188687520

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.

211 : 1, 211

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

242 : 1, 2, 11, 22, 121, 242

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,420,242,988, is 1.

Now, the common factors can be found like this.

211:211

420:2x 2x 3x 5x 7

242:2x 11x 11

988:2x 2x 13x 19

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 21188687520/(1x8)

LCM = 21188687520/8

LCM = 2648585940

Thus, we can understand that the LCM of 211,420,242,988 is 2648585940.
