Given numbers are 691,806,210,242,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,806,210,242,549 is 1294907804190.
Find LCM of 691,806,210,242,549 with Prime Factorization
| 2 | 691, 806, 210, 242, 549 |
| 3 | 691, 403, 105, 121, 549 |
| 691, 403, 35, 121, 183 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 691 x 403 x 35 x 121 x 183 = 1294907804190
Therefore, the lowest common multiple of 691,806,210,242,549 is 1294907804190.
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 806 x 210 x 242 x 549 = 15538893650280
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
242 : 1, 2, 11, 22, 121, 242
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,806,210,242,549, is 1.
Now, the common factors can be found like this.
691:691
806:2x 13x 31
210:2x 3x 5x 7
242:2x 11x 11
549:3x 3x 61
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 3 = 12
Therefore, the value for common factors is 12.
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 = 15538893650280/(1x12)
LCM = 15538893650280/12
LCM = 1294907804190
Thus, we can understand that the LCM of 691,806,210,242,549 is 1294907804190.
