Find LCM of 924,765,391,169,705 with Prime Factorization


3 924, 765, 391, 169, 705
5 308, 255, 391, 169, 235
17 308, 51, 391, 169, 47
308, 3, 23, 169, 47

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

3 x 5 x 17 x 308 x 3 x 23 x 169 x 47 = 43045182180

LCM Formula to Find Lowest Common Multiple of 924,765,391,169,705

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.

924 x 765 x 391 x 169 x 705 = 32929564367700

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.

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

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

391 : 1, 17, 23, 391

169 : 1, 13, 169

705 : 1, 3, 5, 15, 47, 141, 235, 705

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,765,391,169,705, is 1.

Now, the common factors can be found like this.

924:2x 2x 3x 7x 11

765:3x 3x 5x 17

391:17x 23

169:13x 13

705:3x 5x 47

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

3x 3x 5x 17 = 765

Therefore, the value for common factors is 765.

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 = 32929564367700/(1x765)

LCM = 32929564367700/765

LCM = 43045182180

Thus, we can understand that the LCM of 924,765,391,169,705 is 43045182180.
