Given numbers are 693,722,766,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,722,766,990 is 958162590.
Find LCM of 693,722,766,990 with Prime Factorization
| 2 | 693, 722, 766, 990 |
| 3 | 693, 361, 383, 495 |
| 3 | 231, 361, 383, 165 |
| 11 | 77, 361, 383, 55 |
| 7, 361, 383, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 7 x 361 x 383 x 5 = 958162590
Therefore, the lowest common multiple of 693,722,766,990 is 958162590.
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 722 x 766 x 990 = 379432385640
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
722 : 1, 2, 19, 38, 361, 722
766 : 1, 2, 383, 766
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,722,766,990, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
722:2x 19x 19
766:2x 383
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 379432385640/(1x396)
LCM = 379432385640/396
LCM = 958162590
Thus, we can understand that the LCM of 693,722,766,990 is 958162590.
