Given numbers are 991,434,403

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

The LCM of 991,434,403 is 5591222.

Find LCM of 991,434,403 with Prime Factorization

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

31 x 991 x 14 x 13 = 5591222

Therefore, the lowest common multiple of 991,434,403 is 5591222.

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.

991 x 434 x 403 = 173327882

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.

991 : 1, 991

434 : 1, 2, 7, 14, 31, 62, 217, 434

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,434,403, is 1.

Now, the common factors can be found like this.

991:991

434:2x 7x 31

403:13x 31

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

31 = 31

Therefore, the value for common factors is 31.

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 = 173327882/(1x31)

LCM = 173327882/31

LCM = 5591222

Thus, we can understand that the LCM of 991,434,403 is 5591222.

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

• LCM of 225, 161, 216
• LCM of 120, 423, 938
• LCM of 587, 907, 344
