Given numbers are 647,699,981

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

The LCM of 647,699,981 is 147886731.

Find LCM of 647,699,981 with Prime Factorization

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

3 x 647 x 233 x 327 = 147886731

Therefore, the lowest common multiple of 647,699,981 is 147886731.

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.

647 x 699 x 981 = 443660193

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.

647 : 1, 647

699 : 1, 3, 233, 699

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,699,981, is 1.

Now, the common factors can be found like this.

647:647

699:3x 233

981:3x 3x 109

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

3 = 3

Therefore, the value for common factors is 3.

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 = 443660193/(1x3)

LCM = 443660193/3

LCM = 147886731

Thus, we can understand that the LCM of 647,699,981 is 147886731.

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

• LCM of 134, 674, 940
