The LCM of 812,748,978,513 is 12697043436.

Find LCM of 812,748,978,513 with Prime Factorization


2 812, 748, 978, 513
2 406, 374, 489, 513
3 203, 187, 489, 513
203, 187, 163, 171

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

2 x 2 x 3 x 203 x 187 x 163 x 171 = 12697043436

Therefore, the lowest common multiple of 812,748,978,513 is 12697043436.

LCM Formula to Find Lowest Common Multiple of 812,748,978,513

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.

812 x 748 x 978 x 513 = 304729042464

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.

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

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

978 : 1, 2, 3, 6, 163, 326, 489, 978

513 : 1, 3, 9, 19, 27, 57, 171, 513

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,748,978,513, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

748:2x 2x 11x 17

978:2x 3x 163

513:3x 3x 3x 19

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 304729042464/(1x24)

LCM = 304729042464/24

LCM = 12697043436

Thus, we can understand that the LCM of 812,748,978,513 is 12697043436.
