Given numbers are 685,382,252,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,382,252,553 is 2604663180.
Find LCM of 685,382,252,553 with Prime Factorization
| 2 | 685, 382, 252, 553 |
| 7 | 685, 191, 126, 553 |
| 685, 191, 18, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 685 x 191 x 18 x 79 = 2604663180
Therefore, the lowest common multiple of 685,382,252,553 is 2604663180.
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.
685 x 382 x 252 x 553 = 36465284520
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.
685 : 1, 5, 137, 685
382 : 1, 2, 191, 382
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,382,252,553, is 1.
Now, the common factors can be found like this.
685:5x 137
382:2x 191
252:2x 2x 3x 3x 7
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 36465284520/(1x14)
LCM = 36465284520/14
LCM = 2604663180
Thus, we can understand that the LCM of 685,382,252,553 is 2604663180.
