Given numbers are 1,988,989,969

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

The LCM of 1,988,989,969 is 49833732.

Find LCM of 1,988,989,969 with Prime Factorization

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

19 x 1 x 52 x 989 x 51 = 49833732

Therefore, the lowest common multiple of 1,988,989,969 is 49833732.

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.

1 x 988 x 989 x 969 = 946840908

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.

1 : 1

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

989 : 1, 23, 43, 989

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,988,989,969, is 1.

Now, the common factors can be found like this.

1:

988:2x 2x 13x 19

989:23x 43

969:3x 17x 19

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 = 946840908/(1x19)

LCM = 946840908/19

LCM = 49833732

Thus, we can understand that the LCM of 1,988,989,969 is 49833732.
