| 17 | 731, 85, 1, 47, 4 |
| 43, 5, 1, 47, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 7 x 17 x 43 x 5 x 1 x 47 x 4 = 769596800
Therefore, the lowest common multiple of 731,425,224,329,640 is 769596800.
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.
731 x 425 x 224 x 329 x 640 = 14653123072000
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.
731 : 1, 17, 43, 731
425 : 1, 5, 17, 25, 85, 425
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
329 : 1, 7, 47, 329
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,425,224,329,640, is 1.
Now, the common factors can be found like this.
731:17x 43
425:5x 5x 17
224:2x 2x 2x 2x 2x 7
329:7x 47
640:2x 2x 2x 2x 2x 2x 2x 5
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 5x 7x 17 = 19040
Therefore, the value for common factors is 19040.
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 = 14653123072000/(1x19040)
LCM = 14653123072000/19040
LCM = 769596800
Thus, we can understand that the LCM of 731,425,224,329,640 is 769596800.
