Given numbers are 697,451,690,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,451,690,729 is 1285525890.
Find LCM of 697,451,690,729 with Prime Factorization
| 3 | 697, 451, 690, 729 |
| 41 | 697, 451, 230, 243 |
| 17, 11, 230, 243 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 17 x 11 x 230 x 243 = 1285525890
Therefore, the lowest common multiple of 697,451,690,729 is 1285525890.
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.
697 x 451 x 690 x 729 = 158119684470
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.
697 : 1, 17, 41, 697
451 : 1, 11, 41, 451
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,451,690,729, is 1.
Now, the common factors can be found like this.
697:17x 41
451:11x 41
690:2x 3x 5x 23
729:3x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 158119684470/(1x123)
LCM = 158119684470/123
LCM = 1285525890
Thus, we can understand that the LCM of 697,451,690,729 is 1285525890.
