Given numbers are 693,686,647,361,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,686,647,361,469 is 1062785438946.
Find LCM of 693,686,647,361,469 with Prime Factorization
| 7 | 693, 686, 647, 361, 469 |
| 99, 98, 647, 361, 67 |
Multiply the prime numbers at the bottom and the left side.
7 x 99 x 98 x 647 x 361 x 67 = 1062785438946
Therefore, the lowest common multiple of 693,686,647,361,469 is 1062785438946.
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 686 x 647 x 361 x 469 = 52076486508354
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
647 : 1, 647
361 : 1, 19, 361
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,686,647,361,469, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
686:2x 7x 7x 7
647:647
361:19x 19
469:7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 52076486508354/(1x49)
LCM = 52076486508354/49
LCM = 1062785438946
Thus, we can understand that the LCM of 693,686,647,361,469 is 1062785438946.
