Given numbers are 364,640,880,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 364,640,880,687 is 440119680.
Find LCM of 364,640,880,687 with Prime Factorization
| 2 | 364, 640, 880, 687 |
| 2 | 182, 320, 440, 687 |
| 2 | 91, 160, 220, 687 |
| 2 | 91, 80, 110, 687 |
| 5 | 91, 40, 55, 687 |
| 91, 8, 11, 687 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 91 x 8 x 11 x 687 = 440119680
Therefore, the lowest common multiple of 364,640,880,687 is 440119680.
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.
364 x 640 x 880 x 687 = 140838297600
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,640,880,687, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
640:2x 2x 2x 2x 2x 2x 2x 5
880:2x 2x 2x 2x 5x 11
687:3x 229
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 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 140838297600/(1x320)
LCM = 140838297600/320
LCM = 440119680
Thus, we can understand that the LCM of 364,640,880,687 is 440119680.
