Calculate the LCM of 634,170,428,935

Given numbers are 634,170,428,935

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

The LCM of 634,170,428,935 is 126857060.

Find LCM of 634,170,428,935 with Prime Factorization


2 634, 170, 428, 935
5 317, 85, 214, 935
17 317, 17, 214, 187
317, 1, 214, 11

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

2 x 5 x 17 x 317 x 1 x 214 x 11 = 126857060

Therefore, the lowest common multiple of 634,170,428,935 is 126857060.

LCM Formula to Find Lowest Common Multiple of 634,170,428,935

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.

634 x 170 x 428 x 935 = 43131400400

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.

634 : 1, 2, 317, 634

170 : 1, 2, 5, 10, 17, 34, 85, 170

428 : 1, 2, 4, 107, 214, 428

935 : 1, 5, 11, 17, 55, 85, 187, 935

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,170,428,935, is 1.

Now, the common factors can be found like this.

634:2x 317

170:2x 5x 17

428:2x 2x 107

935:5x 11x 17

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 5x 17 = 340

Therefore, the value for common factors is 340.

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 = 43131400400/(1x340)

LCM = 43131400400/340

LCM = 126857060

Thus, we can understand that the LCM of 634,170,428,935 is 126857060.
