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

2 x 2 x 3 x 5 x 13 x 409 x 1 x 5 x 82 = 130798200

Therefore, the lowest common multiple of 409,975,780,984 is 130798200.

LCM Formula to Find Lowest Common Multiple of 409,975,780,984

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.

409 x 975 x 780 x 984 = 306067788000

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.

409 : 1, 409

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,975,780,984, is 1.

Now, the common factors can be found like this.

409:409

975:3x 5x 5x 13

780:2x 2x 3x 5x 13

984:2x 2x 2x 3x 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 3x 3x 5x 13 = 2340

Therefore, the value for common factors is 2340.

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 = 306067788000/(1x2340)

LCM = 306067788000/2340

LCM = 130798200

Thus, we can understand that the LCM of 409,975,780,984 is 130798200.
