Given numbers are 971,554,120,991

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

The LCM of 971,554,120,991 is 31985555640.

Find LCM of 971,554,120,991 with Prime Factorization

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

2 x 971 x 277 x 60 x 991 = 31985555640

Therefore, the lowest common multiple of 971,554,120,991 is 31985555640.

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 554 x 120 x 991 = 63971111280

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

554 : 1, 2, 277, 554

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,554,120,991, is 1.

Now, the common factors can be found like this.

971:971

554:2x 277

120:2x 2x 2x 3x 5

991:991

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

2 = 2

Therefore, the value for common factors is 2.

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 = 63971111280/(1x2)

LCM = 63971111280/2

LCM = 31985555640

Thus, we can understand that the LCM of 971,554,120,991 is 31985555640.
