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

2 x 2 x 2 x 3 x 3 x 3 x 3 x 253 x 1 x 3 x 4 = 1967328

Therefore, the lowest common multiple of 253,243,648,864 is 1967328.

LCM Formula to Find Lowest Common Multiple of 253,243,648,864

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.

253 x 243 x 648 x 864 = 34420370688

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.

253 : 1, 11, 23, 253

243 : 1, 3, 9, 27, 81, 243

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,243,648,864, is 1.

Now, the common factors can be found like this.

253:11x 23

243:3x 3x 3x 3x 3

648:2x 2x 2x 3x 3x 3x 3

864:2x 2x 2x 2x 2x 3x 3x 3

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 3x 3x 3x 3x 3x 3x 3 = 17496

Therefore, the value for common factors is 17496.

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 = 34420370688/(1x17496)

LCM = 34420370688/17496

LCM = 1967328

Thus, we can understand that the LCM of 253,243,648,864 is 1967328.
