The LCM of 247,186,552,621 is 38039976.

Find LCM of 247,186,552,621 with Prime Factorization


2 247, 186, 552, 621
3 247, 93, 276, 621
23 247, 31, 92, 207
247, 31, 4, 9

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

2 x 3 x 23 x 247 x 31 x 4 x 9 = 38039976

Therefore, the lowest common multiple of 247,186,552,621 is 38039976.

LCM Formula to Find Lowest Common Multiple of 247,186,552,621

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.

247 x 186 x 552 x 621 = 15748550064

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.

247 : 1, 13, 19, 247

186 : 1, 2, 3, 6, 31, 62, 93, 186

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,186,552,621, is 1.

Now, the common factors can be found like this.

247:13x 19

186:2x 3x 31

552:2x 2x 2x 3x 23

621:3x 3x 3x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3x 23 = 414

Therefore, the value for common factors is 414.

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 = 15748550064/(1x414)

LCM = 15748550064/414

LCM = 38039976

Thus, we can understand that the LCM of 247,186,552,621 is 38039976.
