The LCM of 838,206,765,812 is 26808265260.

Find LCM of 838,206,765,812 with Prime Factorization


2 838, 206, 765, 812
419, 103, 765, 406

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

2 x 419 x 103 x 765 x 406 = 26808265260

Therefore, the lowest common multiple of 838,206,765,812 is 26808265260.

LCM Formula to Find Lowest Common Multiple of 838,206,765,812

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.

838 x 206 x 765 x 812 = 107233061040

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.

838 : 1, 2, 419, 838

206 : 1, 2, 103, 206

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,206,765,812, is 1.

Now, the common factors can be found like this.

838:2x 419

206:2x 103

765:3x 3x 5x 17

812:2x 2x 7x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 107233061040/(1x4)

LCM = 107233061040/4

LCM = 26808265260

Thus, we can understand that the LCM of 838,206,765,812 is 26808265260.
