Given numbers are 685,340,609,464,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,340,609,464,278 is 15772174320.
Find LCM of 685,340,609,464,278 with Prime Factorization
| 2 | 685, 340, 609, 464, 278 |
| 2 | 685, 170, 609, 232, 139 |
| 5 | 685, 85, 609, 116, 139 |
| 29 | 137, 17, 609, 116, 139 |
| 137, 17, 21, 4, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 137 x 17 x 21 x 4 x 139 = 15772174320
Therefore, the lowest common multiple of 685,340,609,464,278 is 15772174320.
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 340 x 609 x 464 x 278 = 18295722211200
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
609 : 1, 3, 7, 21, 29, 87, 203, 609
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,340,609,464,278, is 1.
Now, the common factors can be found like this.
685:5x 137
340:2x 2x 5x 17
609:3x 7x 29
464:2x 2x 2x 2x 29
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 29 = 1160
Therefore, the value for common factors is 1160.
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 = 18295722211200/(1x1160)
LCM = 18295722211200/1160
LCM = 15772174320
Thus, we can understand that the LCM of 685,340,609,464,278 is 15772174320.
