Given numbers are 841,189,190,842

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

The LCM of 841,189,190,842 is 12714330510.

Find LCM of 841,189,190,842 with Prime Factorization

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

2 x 841 x 189 x 95 x 421 = 12714330510

Therefore, the lowest common multiple of 841,189,190,842 is 12714330510.

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 189 x 190 x 842 = 25428661020

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

189 : 1, 3, 7, 9, 21, 27, 63, 189

190 : 1, 2, 5, 10, 19, 38, 95, 190

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,189,190,842, is 1.

Now, the common factors can be found like this.

841:29x 29

189:3x 3x 3x 7

190:2x 5x 19

842:2x 421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 25428661020/(1x2)

LCM = 25428661020/2

LCM = 12714330510

Thus, we can understand that the LCM of 841,189,190,842 is 12714330510.
