Given numbers are 841,20,265,615

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

The LCM of 841,20,265,615 is 109649580.

Find LCM of 841,20,265,615 with Prime Factorization

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

5 x 841 x 4 x 53 x 123 = 109649580

Therefore, the lowest common multiple of 841,20,265,615 is 109649580.

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 20 x 265 x 615 = 2741239500

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

20 : 1, 2, 4, 5, 10, 20

265 : 1, 5, 53, 265

615 : 1, 3, 5, 15, 41, 123, 205, 615

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,20,265,615, is 1.

Now, the common factors can be found like this.

841:29x 29

20:2x 2x 5

265:5x 53

615:3x 5x 41

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 2741239500/(1x25)

LCM = 2741239500/25

LCM = 109649580

Thus, we can understand that the LCM of 841,20,265,615 is 109649580.
