Given numbers are 168,422,211,971

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

The LCM of 168,422,211,971 is 34420008.

Find LCM of 168,422,211,971 with Prime Factorization

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

2 x 211 x 84 x 1 x 1 x 971 = 34420008

Therefore, the lowest common multiple of 168,422,211,971 is 34420008.

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.

168 x 422 x 211 x 971 = 14525243376

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

422 : 1, 2, 211, 422

211 : 1, 211

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,422,211,971, is 1.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

422:2x 211

211:211

971:971

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

2x 211 = 422

Therefore, the value for common factors is 422.

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 = 14525243376/(1x422)

LCM = 14525243376/422

LCM = 34420008

Thus, we can understand that the LCM of 168,422,211,971 is 34420008.
