Given numbers are 693,898,393,441,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,898,393,441,945 is 8559929070.
Find LCM of 693,898,393,441,945 with Prime Factorization
| 3 | 693, 898, 393, 441, 945 |
| 3 | 231, 898, 131, 147, 315 |
| 7 | 77, 898, 131, 49, 105 |
| 11, 898, 131, 7, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 898 x 131 x 7 x 15 = 8559929070
Therefore, the lowest common multiple of 693,898,393,441,945 is 8559929070.
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.
693 x 898 x 393 x 441 x 945 = 101923075436490
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
898 : 1, 2, 449, 898
393 : 1, 3, 131, 393
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,898,393,441,945, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
898:2x 449
393:3x 131
441:3x 3x 7x 7
945:3x 3x 3x 5x 7
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 3x 3x 3x 7x 7 = 11907
Therefore, the value for common factors is 11907.
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 = 101923075436490/(1x11907)
LCM = 101923075436490/11907
LCM = 8559929070
Thus, we can understand that the LCM of 693,898,393,441,945 is 8559929070.
