The LCM of 217,357,575,945,823 is 47134629675.
Find LCM of 217,357,575,945,823 with Prime Factorization
| 3 | 217, 357, 575, 945, 823 |
| 5 | 217, 119, 575, 315, 823 |
| 7 | 217, 119, 115, 63, 823 |
| 31, 17, 115, 9, 823 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 31 x 17 x 115 x 9 x 823 = 47134629675
Therefore, the lowest common multiple of 217,357,575,945,823 is 47134629675.
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.
217 x 357 x 575 x 945 x 823 = 34643952811125
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.
217 : 1, 7, 31, 217
357 : 1, 3, 7, 17, 21, 51, 119, 357
575 : 1, 5, 23, 25, 115, 575
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
823 : 1, 823
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,357,575,945,823, is 1.
Now, the common factors can be found like this.
217:7x 31
357:3x 7x 17
575:5x 5x 23
945:3x 3x 3x 5x 7
823:823
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 7 = 735
Therefore, the value for common factors is 735.
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 = 34643952811125/(1x735)
LCM = 34643952811125/735
LCM = 47134629675
Thus, we can understand that the LCM of 217,357,575,945,823 is 47134629675.
