Given numbers are 971,119,646,989

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

The LCM of 971,119,646,989 is 4342562518.

Find LCM of 971,119,646,989 with Prime Factorization

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

17 x 971 x 7 x 38 x 989 = 4342562518

Therefore, the lowest common multiple of 971,119,646,989 is 4342562518.

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.

971 x 119 x 646 x 989 = 73823562806

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.

971 : 1, 971

119 : 1, 7, 17, 119

646 : 1, 2, 17, 19, 34, 38, 323, 646

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,119,646,989, is 1.

Now, the common factors can be found like this.

971:971

119:7x 17

646:2x 17x 19

989:23x 43

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

17 = 17

Therefore, the value for common factors is 17.

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 = 73823562806/(1x17)

LCM = 73823562806/17

LCM = 4342562518

Thus, we can understand that the LCM of 971,119,646,989 is 4342562518.
