Given numbers are 841,228,209,421

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

The LCM of 841,228,209,421 is 887984988.

Find LCM of 841,228,209,421 with Prime Factorization

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

19 x 841 x 12 x 11 x 421 = 887984988

Therefore, the lowest common multiple of 841,228,209,421 is 887984988.

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.

841 x 228 x 209 x 421 = 16871714772

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.

841 : 1, 29, 841

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

209 : 1, 11, 19, 209

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,228,209,421, is 1.

Now, the common factors can be found like this.

841:29x 29

228:2x 2x 3x 19

209:11x 19

421:421

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

19 = 19

Therefore, the value for common factors is 19.

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 = 16871714772/(1x19)

LCM = 16871714772/19

LCM = 887984988

Thus, we can understand that the LCM of 841,228,209,421 is 887984988.
