Find LCM of 693,261,987,399,901 with Prime Factorization
| 3 | 693, 261, 987, 399, 901 |
| 3 | 231, 87, 329, 133, 901 |
| 7 | 77, 29, 329, 133, 901 |
| 11, 29, 47, 19, 901 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 29 x 47 x 19 x 901 = 16169905521
Therefore, the lowest common multiple of 693,261,987,399,901 is 16169905521.
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.
693 x 261 x 987 x 399 x 901 = 64178355012849
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
261 : 1, 3, 9, 29, 87, 261
987 : 1, 3, 7, 21, 47, 141, 329, 987
399 : 1, 3, 7, 19, 21, 57, 133, 399
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,261,987,399,901, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
261:3x 3x 29
987:3x 7x 47
399:3x 7x 19
901:17x 53
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 3x 7x 7 = 3969
Therefore, the value for common factors is 3969.
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 = 64178355012849/(1x3969)
LCM = 64178355012849/3969
LCM = 16169905521
Thus, we can understand that the LCM of 693,261,987,399,901 is 16169905521.
