The LCM of 774,162,306,423 is 5565834.

Find LCM of 774,162,306,423 with Prime Factorization


2 774, 162, 306, 423
3 387, 81, 153, 423
3 129, 27, 51, 141
43, 9, 17, 47

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

2 x 3 x 3 x 43 x 9 x 17 x 47 = 5565834

Therefore, the lowest common multiple of 774,162,306,423 is 5565834.

LCM Formula to Find Lowest Common Multiple of 774,162,306,423

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.

774 x 162 x 306 x 423 = 16229971944

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

423 : 1, 3, 9, 47, 141, 423

9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,162,306,423, is 9.

Now, the common factors can be found like this.

774:2x 3x 3x 43

162:2x 3x 3x 3x 3

306:2x 3x 3x 17

423:3x 3x 47

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 3x 3x 3 = 324

Therefore, the value for common factors is 324.

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 = 16229971944/(9x324)

LCM = 16229971944/2916

LCM = 5565834

Thus, we can understand that the LCM of 774,162,306,423 is 5565834.
