Given numbers are 437,345,697,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,345,697,861 is 31981845.
Find LCM of 437,345,697,861 with Prime Factorization
| 3 | 437, 345, 697, 861 |
| 23 | 437, 115, 697, 287 |
| 41 | 19, 5, 697, 287 |
| 19, 5, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 41 x 19 x 5 x 17 x 7 = 31981845
Therefore, the lowest common multiple of 437,345,697,861 is 31981845.
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.
437 x 345 x 697 x 861 = 90476639505
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.
437 : 1, 19, 23, 437
345 : 1, 3, 5, 15, 23, 69, 115, 345
697 : 1, 17, 41, 697
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,345,697,861, is 1.
Now, the common factors can be found like this.
437:19x 23
345:3x 5x 23
697:17x 41
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23x 41 = 2829
Therefore, the value for common factors is 2829.
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 = 90476639505/(1x2829)
LCM = 90476639505/2829
LCM = 31981845
Thus, we can understand that the LCM of 437,345,697,861 is 31981845.
