The LCM of 321,168,104,628 is 36689016.

Find LCM of 321,168,104,628 with Prime Factorization


2 321, 168, 104, 628
2 321, 84, 52, 314
2 321, 42, 26, 157
3 321, 21, 13, 157
107, 7, 13, 157

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

2 x 2 x 2 x 3 x 107 x 7 x 13 x 157 = 36689016

Therefore, the lowest common multiple of 321,168,104,628 is 36689016.

LCM Formula to Find Lowest Common Multiple of 321,168,104,628

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.

321 x 168 x 104 x 628 = 3522145536

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.

321 : 1, 3, 107, 321

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

104 : 1, 2, 4, 8, 13, 26, 52, 104

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,168,104,628, is 1.

Now, the common factors can be found like this.

321:3x 107

168:2x 2x 2x 3x 7

104:2x 2x 2x 13

628:2x 2x 157

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 2x 2x 2x 3 = 96

Therefore, the value for common factors is 96.

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 = 3522145536/(1x96)

LCM = 3522145536/96

LCM = 36689016

Thus, we can understand that the LCM of 321,168,104,628 is 36689016.
