Given numbers are 86,989,971

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

The LCM of 86,989,971 is 1920638.

Find LCM of 86,989,971 with Prime Factorization

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

43 x 2 x 23 x 971 = 1920638

Therefore, the lowest common multiple of 86,989,971 is 1920638.

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.

86 x 989 x 971 = 82587434

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.

86 : 1, 2, 43, 86

989 : 1, 23, 43, 989

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 86,989,971, is 1.

Now, the common factors can be found like this.

86:2x 43

989:23x 43

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.

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 = 82587434/(1x43)

LCM = 82587434/43

LCM = 1920638

Thus, we can understand that the LCM of 86,989,971 is 1920638.

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

• LCM of 14, 892, 410
• LCM of 57, 212, 758
