Calculate the LCM of 430,646,403,988

Given numbers are 430,646,403,988

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

The LCM of 430,646,403,988 is 111945340.

Find LCM of 430,646,403,988 with Prime Factorization


2 430, 646, 403, 988
13 215, 323, 403, 494
19 215, 323, 31, 38
215, 17, 31, 2

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

2 x 13 x 19 x 215 x 17 x 31 x 2 = 111945340

Therefore, the lowest common multiple of 430,646,403,988 is 111945340.

LCM Formula to Find Lowest Common Multiple of 430,646,403,988

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.

430 x 646 x 403 x 988 = 110601995920

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.

430 : 1, 2, 5, 10, 43, 86, 215, 430

646 : 1, 2, 17, 19, 34, 38, 323, 646

403 : 1, 13, 31, 403

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,646,403,988, is 1.

Now, the common factors can be found like this.

430:2x 5x 43

646:2x 17x 19

403:13x 31

988:2x 2x 13x 19

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

2x 2x 13x 19 = 988

Therefore, the value for common factors is 988.

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 = 110601995920/(1x988)

LCM = 110601995920/988

LCM = 111945340

Thus, we can understand that the LCM of 430,646,403,988 is 111945340.
