Given numbers are 77,431,231

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

The LCM of 77,431,231 is 99561.

Find LCM of 77,431,231 with Prime Factorization

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

7 x 11 x 1 x 431 x 3 = 99561

Therefore, the lowest common multiple of 77,431,231 is 99561.

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.

77 x 431 x 231 = 7666197

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.

77 : 1, 7, 11, 77

431 : 1, 431

231 : 1, 3, 7, 11, 21, 33, 77, 231

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,431,231, is 1.

Now, the common factors can be found like this.

77:7x 11

431:431

231:3x 7x 11

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

7x 11 = 77

Therefore, the value for common factors is 77.

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 = 7666197/(1x77)

LCM = 7666197/77

LCM = 99561

Thus, we can understand that the LCM of 77,431,231 is 99561.

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

• LCM of 54, 463, 750
• LCM of 20, 729, 607
