The LCM of 347,972,585,945 is 153464220.
Find LCM of 347,972,585,945 with Prime Factorization
| 3 | 347, 972, 585, 945 |
| 3 | 347, 324, 195, 315 |
| 3 | 347, 108, 65, 105 |
| 5 | 347, 36, 65, 35 |
| 347, 36, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 347 x 36 x 13 x 7 = 153464220
Therefore, the lowest common multiple of 347,972,585,945 is 153464220.
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.
347 x 972 x 585 x 945 = 186459027300
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.
347 : 1, 347
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
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 347,972,585,945, is 1.
Now, the common factors can be found like this.
347:347
972:2x 2x 3x 3x 3x 3x 3
585:3x 3x 5x 13
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 5 = 1215
Therefore, the value for common factors is 1215.
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 = 186459027300/(1x1215)
LCM = 186459027300/1215
LCM = 153464220
Thus, we can understand that the LCM of 347,972,585,945 is 153464220.
