Given numbers are 438,340,640,592
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,340,640,592 is 88160640.
Find LCM of 438,340,640,592 with Prime Factorization
| 2 | 438, 340, 640, 592 |
| 2 | 219, 170, 320, 296 |
| 2 | 219, 85, 160, 148 |
| 2 | 219, 85, 80, 74 |
| 5 | 219, 85, 40, 37 |
| 219, 17, 8, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 219 x 17 x 8 x 37 = 88160640
Therefore, the lowest common multiple of 438,340,640,592 is 88160640.
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.
438 x 340 x 640 x 592 = 56422809600
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,340,640,592, is 2.
Now, the common factors can be found like this.
438:2x 3x 73
340:2x 2x 5x 17
640:2x 2x 2x 2x 2x 2x 2x 5
592:2x 2x 2x 2x 37
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 = 56422809600/(2x320)
LCM = 56422809600/640
LCM = 88160640
Thus, we can understand that the LCM of 438,340,640,592 is 88160640.
