Given numbers are 699,605,649,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,605,649,691 is 17241006255.
Find LCM of 699,605,649,691 with Prime Factorization
| 11 | 699, 605, 649, 691 |
| 699, 55, 59, 691 |
Multiply the prime numbers at the bottom and the left side.
11 x 699 x 55 x 59 x 691 = 17241006255
Therefore, the lowest common multiple of 699,605,649,691 is 17241006255.
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.
699 x 605 x 649 x 691 = 189651068805
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.
699 : 1, 3, 233, 699
605 : 1, 5, 11, 55, 121, 605
649 : 1, 11, 59, 649
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,605,649,691, is 1.
Now, the common factors can be found like this.
699:3x 233
605:5x 11x 11
649:11x 59
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 189651068805/(1x11)
LCM = 189651068805/11
LCM = 17241006255
Thus, we can understand that the LCM of 699,605,649,691 is 17241006255.
