Find LCM of 169,942,585,865,621 with Prime Factorization
| 3 | 169, 942, 585, 865, 621 |
| 3 | 169, 314, 195, 865, 207 |
| 5 | 169, 314, 65, 865, 69 |
| 13 | 169, 314, 13, 173, 69 |
| 1, 314, 13, 173, 69 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 1 x 314 x 13 x 173 x 69 = 28505197890
Therefore, the lowest common multiple of 169,942,585,865,621 is 28505197890.
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.
169 x 942 x 585 x 865 x 621 = 50026622296950
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.
169 : 1, 13, 169
942 : 1, 2, 3, 6, 157, 314, 471, 942
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
865 : 1, 5, 173, 865
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,942,585,865,621, is 1.
Now, the common factors can be found like this.
169:13x 13
942:2x 3x 157
585:3x 3x 5x 13
865:5x 173
621:3x 3x 3x 23
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 3x 5x 13 = 1755
Therefore, the value for common factors is 1755.
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 = 50026622296950/(1x1755)
LCM = 50026622296950/1755
LCM = 28505197890
Thus, we can understand that the LCM of 169,942,585,865,621 is 28505197890.
