Given numbers are 989,2021

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

The LCM of 989,2021 is 46483.

Find LCM of 989,2021 with Prime Factorization

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

43 x 23 x 47 = 46483

Therefore, the lowest common multiple of 989,2021 is 46483.

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.

989 x 2021 = 1998769

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.

989 : 1, 23, 43, 989

2021 : 1, 43, 47, 2021

43 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,2021, is 43.

Now, the common factors can be found like this.

989:23x 43

2021:43x 47

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 = 1998769/(43x1)

LCM = 1998769/43

LCM = 46483

Thus, we can understand that the LCM of 989,2021 is 46483.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 180, 1045
• LCM of 777, 3067
