Find LCM of 161,976,518,636,405 with Prime Factorization


2 161, 976, 518, 636, 405
2 161, 488, 259, 318, 405
3 161, 244, 259, 159, 405
7 161, 244, 259, 53, 135
23, 244, 37, 53, 135

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

2 x 2 x 3 x 7 x 23 x 244 x 37 x 53 x 135 = 124798196880

Therefore, the lowest common multiple of 161,976,518,636,405 is 124798196880.

LCM Formula to Find Lowest Common Multiple of 161,976,518,636,405

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.

161 x 976 x 518 x 636 x 405 = 20966097075840

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.

161 : 1, 7, 23, 161

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

518 : 1, 2, 7, 14, 37, 74, 259, 518

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,976,518,636,405, is 1.

Now, the common factors can be found like this.

161:7x 23

976:2x 2x 2x 2x 61

518:2x 7x 37

636:2x 2x 3x 53

405:3x 3x 3x 3x 5

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 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 20966097075840/(1x168)

LCM = 20966097075840/168

LCM = 124798196880

Thus, we can understand that the LCM of 161,976,518,636,405 is 124798196880.
