Given numbers are 693,379,871,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,379,871,435 is 33171002865.
Find LCM of 693,379,871,435 with Prime Factorization
| 3 | 693, 379, 871, 435 |
| 231, 379, 871, 145 |
Multiply the prime numbers at the bottom and the left side.
3 x 231 x 379 x 871 x 145 = 33171002865
Therefore, the lowest common multiple of 693,379,871,435 is 33171002865.
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 379 x 871 x 435 = 99513008595
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
379 : 1, 379
871 : 1, 13, 67, 871
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,379,871,435, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
379:379
871:13x 67
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 99513008595/(1x3)
LCM = 99513008595/3
LCM = 33171002865
Thus, we can understand that the LCM of 693,379,871,435 is 33171002865.
