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

2 x 2 x 3 x 5 x 7 x 29 x 13 x 15 x 167 = 396641700

Therefore, the lowest common multiple of 609,455,900,668 is 396641700.

LCM Formula to Find Lowest Common Multiple of 609,455,900,668

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.

609 x 455 x 900 x 668 = 166589514000

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

455 : 1, 5, 7, 13, 35, 65, 91, 455

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,455,900,668, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

455:5x 7x 13

900:2x 2x 3x 3x 5x 5

668:2x 2x 167

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 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 166589514000/(1x420)

LCM = 166589514000/420

LCM = 396641700

Thus, we can understand that the LCM of 609,455,900,668 is 396641700.
