Given numbers are 691,665,681,489,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,665,681,489,986 is 50293437935370.
Find LCM of 691,665,681,489,986 with Prime Factorization
| 3 | 691, 665, 681, 489, 986 |
| 691, 665, 227, 163, 986 |
Multiply the prime numbers at the bottom and the left side.
3 x 691 x 665 x 227 x 163 x 986 = 50293437935370
Therefore, the lowest common multiple of 691,665,681,489,986 is 50293437935370.
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.
691 x 665 x 681 x 489 x 986 = 150880313806110
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.
691 : 1, 691
665 : 1, 5, 7, 19, 35, 95, 133, 665
681 : 1, 3, 227, 681
489 : 1, 3, 163, 489
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,665,681,489,986, is 1.
Now, the common factors can be found like this.
691:691
665:5x 7x 19
681:3x 227
489:3x 163
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 150880313806110/(1x3)
LCM = 150880313806110/3
LCM = 50293437935370
Thus, we can understand that the LCM of 691,665,681,489,986 is 50293437935370.
