Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 3 x 1 x 1 x 784 x 449 = 256619664
Therefore, the lowest common multiple of 729,729,784,449 is 256619664.
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.
729 x 729 x 784 x 449 = 187075735056
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.
729 : 1, 3, 9, 27, 81, 243, 729
729 : 1, 3, 9, 27, 81, 243, 729
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,729,784,449, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
729:3x 3x 3x 3x 3x 3
784:2x 2x 2x 2x 7x 7
449:449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 187075735056/(1x729)
LCM = 187075735056/729
LCM = 256619664
Thus, we can understand that the LCM of 729,729,784,449 is 256619664.
