Given numbers are 1963,1638

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

The LCM of 1963,1638 is 247338.

Find LCM of 1963,1638 with Prime Factorization

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

13 x 151 x 126 = 247338

Therefore, the lowest common multiple of 1963,1638 is 247338.

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.

1963 x 1638 = 3215394

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.

1963 : 1, 13, 151, 1963

1638 : 1, 2, 3, 6, 7, 9, 13, 14, 18, 21, 26, 39, 42, 63, 78, 91, 117, 126, 182, 234, 273, 546, 819, 1638

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1963,1638, is 13.

Now, the common factors can be found like this.

1963:13x 151

1638:2x 3x 3x 7x 13

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

= 1

Therefore, the value for common factors is 1.

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 = 3215394/(13x1)

LCM = 3215394/13

LCM = 247338

Thus, we can understand that the LCM of 1963,1638 is 247338.
