The LCM of 685,390,297,192,322 is 27251864640.

Find LCM of 685,390,297,192,322 with Prime Factorization


2 685, 390, 297, 192, 322
3 685, 195, 297, 96, 161
5 685, 65, 99, 32, 161
137, 13, 99, 32, 161

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

2 x 3 x 5 x 137 x 13 x 99 x 32 x 161 = 27251864640

Therefore, the lowest common multiple of 685,390,297,192,322 is 27251864640.

LCM Formula to Find Lowest Common Multiple of 685,390,297,192,322

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.

685 x 390 x 297 x 192 x 322 = 4905335635200

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.

685 : 1, 5, 137, 685

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

297 : 1, 3, 9, 11, 27, 33, 99, 297

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

322 : 1, 2, 7, 14, 23, 46, 161, 322

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,390,297,192,322, is 1.

Now, the common factors can be found like this.

685:5x 137

390:2x 3x 5x 13

297:3x 3x 3x 11

192:2x 2x 2x 2x 2x 2x 3

322:2x 7x 23

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 4905335635200/(1x180)

LCM = 4905335635200/180

LCM = 27251864640

Thus, we can understand that the LCM of 685,390,297,192,322 is 27251864640.
