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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 7 x 247 x 5 x 1 x 17 = 18811520

Therefore, the lowest common multiple of 247,640,896,238 is 18811520.

LCM Formula to Find Lowest Common Multiple of 247,640,896,238

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.

247 x 640 x 896 x 238 = 33710243840

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.

247 : 1, 13, 19, 247

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

238 : 1, 2, 7, 14, 17, 34, 119, 238

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,640,896,238, is 1.

Now, the common factors can be found like this.

247:13x 19

640:2x 2x 2x 2x 2x 2x 2x 5

896:2x 2x 2x 2x 2x 2x 2x 7

238:2x 7x 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 2x 2x 2x 2x 2x 2x 7 = 1792

Therefore, the value for common factors is 1792.

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 = 33710243840/(1x1792)

LCM = 33710243840/1792

LCM = 18811520

Thus, we can understand that the LCM of 247,640,896,238 is 18811520.
