Given numbers are 731,437,693,121,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,437,693,121,810 is 219163003290.
Find LCM of 731,437,693,121,810 with Prime Factorization
| 3 | 731, 437, 693, 121, 810 |
| 3 | 731, 437, 231, 121, 270 |
| 11 | 731, 437, 77, 121, 90 |
| 731, 437, 7, 11, 90 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 731 x 437 x 7 x 11 x 90 = 219163003290
Therefore, the lowest common multiple of 731,437,693,121,810 is 219163003290.
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.
731 x 437 x 693 x 121 x 810 = 21697137325710
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.
731 : 1, 17, 43, 731
437 : 1, 19, 23, 437
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
121 : 1, 11, 121
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,437,693,121,810, is 1.
Now, the common factors can be found like this.
731:17x 43
437:19x 23
693:3x 3x 7x 11
121:11x 11
810:2x 3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 21697137325710/(1x99)
LCM = 21697137325710/99
LCM = 219163003290
Thus, we can understand that the LCM of 731,437,693,121,810 is 219163003290.
