Given numbers are 693,964,921,905,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,964,921,905,342 is 3526556320980.
Find LCM of 693,964,921,905,342 with Prime Factorization
| 2 | 693, 964, 921, 905, 342 |
| 3 | 693, 482, 921, 905, 171 |
| 3 | 231, 482, 307, 905, 57 |
| 77, 482, 307, 905, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 77 x 482 x 307 x 905 x 19 = 3526556320980
Therefore, the lowest common multiple of 693,964,921,905,342 is 3526556320980.
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 964 x 921 x 905 x 342 = 190434041332920
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
964 : 1, 2, 4, 241, 482, 964
921 : 1, 3, 307, 921
905 : 1, 5, 181, 905
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,964,921,905,342, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
964:2x 2x 241
921:3x 307
905:5x 181
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 190434041332920/(1x54)
LCM = 190434041332920/54
LCM = 3526556320980
Thus, we can understand that the LCM of 693,964,921,905,342 is 3526556320980.
