The LCM of 128,180,565,699 is 151655040.

Find LCM of 128,180,565,699 with Prime Factorization


2 128, 180, 565, 699
2 64, 90, 565, 699
3 32, 45, 565, 699
5 32, 15, 565, 233
32, 3, 113, 233

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

2 x 2 x 3 x 5 x 32 x 3 x 113 x 233 = 151655040

Therefore, the lowest common multiple of 128,180,565,699 is 151655040.

LCM Formula to Find Lowest Common Multiple of 128,180,565,699

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.

128 x 180 x 565 x 699 = 9099302400

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

565 : 1, 5, 113, 565

699 : 1, 3, 233, 699

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,180,565,699, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

180:2x 2x 3x 3x 5

565:5x 113

699:3x 233

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 5 = 60

Therefore, the value for common factors is 60.

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 = 9099302400/(1x60)

LCM = 9099302400/60

LCM = 151655040

Thus, we can understand that the LCM of 128,180,565,699 is 151655040.
