The LCM of 646,485,517,953,470 is 154368150310.
Find LCM of 646,485,517,953,470 with Prime Factorization
| 2 | 646, 485, 517, 953, 470 |
| 5 | 323, 485, 517, 953, 235 |
| 47 | 323, 97, 517, 953, 47 |
| 323, 97, 11, 953, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 47 x 323 x 97 x 11 x 953 x 1 = 154368150310
Therefore, the lowest common multiple of 646,485,517,953,470 is 154368150310.
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.
646 x 485 x 517 x 953 x 470 = 72553030645700
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
485 : 1, 5, 97, 485
517 : 1, 11, 47, 517
953 : 1, 953
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,485,517,953,470, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
485:5x 97
517:11x 47
953:953
470:2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 47 = 470
Therefore, the value for common factors is 470.
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 = 72553030645700/(1x470)
LCM = 72553030645700/470
LCM = 154368150310
Thus, we can understand that the LCM of 646,485,517,953,470 is 154368150310.
