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 673 x 3 x 79 x 5 = 102080640

Therefore, the lowest common multiple of 673,384,158,640 is 102080640.

LCM Formula to Find Lowest Common Multiple of 673,384,158,640

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.

673 x 384 x 158 x 640 = 26132643840

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.

673 : 1, 673

384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384

158 : 1, 2, 79, 158

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,384,158,640, is 1.

Now, the common factors can be found like this.

673:673

384:2x 2x 2x 2x 2x 2x 2x 3

158:2x 79

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

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 2 = 256

Therefore, the value for common factors is 256.

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 = 26132643840/(1x256)

LCM = 26132643840/256

LCM = 102080640

Thus, we can understand that the LCM of 673,384,158,640 is 102080640.
