Given numbers are 693,747,168,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,747,168,289 is 132983928.
Find LCM of 693,747,168,289 with Prime Factorization
3 | 693, 747, 168, 289 |
3 | 231, 249, 56, 289 |
7 | 77, 83, 56, 289 |
11, 83, 8, 289 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 83 x 8 x 289 = 132983928
Therefore, the lowest common multiple of 693,747,168,289 is 132983928.
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 747 x 168 x 289 = 25133962392
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
747 : 1, 3, 9, 83, 249, 747
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,747,168,289, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
747:3x 3x 83
168:2x 2x 2x 3x 7
289:17x 17
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 7 = 189
Therefore, the value for common factors is 189.
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 = 25133962392/(1x189)
LCM = 25133962392/189
LCM = 132983928
Thus, we can understand that the LCM of 693,747,168,289 is 132983928.
