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

2 x 2 x 2 x 2 x 2 x 2 x 7 x 407 x 1 x 10 x 991 x 41 = 74084940160

Therefore, the lowest common multiple of 814,448,640,991,287 is 74084940160.

LCM Formula to Find Lowest Common Multiple of 814,448,640,991,287

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.

814 x 448 x 640 x 991 x 287 = 66380106383360

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.

814 : 1, 2, 11, 22, 37, 74, 407, 814

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

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

991 : 1, 991

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,448,640,991,287, is 1.

Now, the common factors can be found like this.

814:2x 11x 37

448:2x 2x 2x 2x 2x 2x 7

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

991:991

287:7x 41

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 7 = 896

Therefore, the value for common factors is 896.

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 = 66380106383360/(1x896)

LCM = 66380106383360/896

LCM = 74084940160

Thus, we can understand that the LCM of 814,448,640,991,287 is 74084940160.
