Given numbers are 971,989,172

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

The LCM of 971,989,172 is 3841276.

Find LCM of 971,989,172 with Prime Factorization

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

43 x 971 x 23 x 4 = 3841276

Therefore, the lowest common multiple of 971,989,172 is 3841276.

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 989 x 172 = 165174868

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

989 : 1, 23, 43, 989

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,989,172, is 1.

Now, the common factors can be found like this.

971:971

989:23x 43

172:2x 2x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 165174868/(1x43)

LCM = 165174868/43

LCM = 3841276

Thus, we can understand that the LCM of 971,989,172 is 3841276.

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

• LCM of 125, 274, 301
• LCM of 517, 165, 597
• LCM of 638, 132, 188
