Given numbers are 529,690,691,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 529,690,691,765 is 559274670.
Find LCM of 529,690,691,765 with Prime Factorization
| 3 | 529, 690, 691, 765 |
| 5 | 529, 230, 691, 255 |
| 23 | 529, 46, 691, 51 |
| 23, 2, 691, 51 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 23 x 2 x 691 x 51 = 559274670
Therefore, the lowest common multiple of 529,690,691,765 is 559274670.
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.
529 x 690 x 691 x 765 = 192949761150
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.
529 : 1, 23, 529
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
691 : 1, 691
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 529,690,691,765, is 1.
Now, the common factors can be found like this.
529:23x 23
690:2x 3x 5x 23
691:691
765:3x 3x 5x 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 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 192949761150/(1x345)
LCM = 192949761150/345
LCM = 559274670
Thus, we can understand that the LCM of 529,690,691,765 is 559274670.
