Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 5 x 797 x 1 x 431 x 11 x 3 = 18363884220
Therefore, the lowest common multiple of 797,405,431,660,972 is 18363884220.
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.
797 x 405 x 431 x 660 x 972 = 89248477309200
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.
797 : 1, 797
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
431 : 1, 431
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,405,431,660,972, is 1.
Now, the common factors can be found like this.
797:797
405:3x 3x 3x 3x 5
431:431
660:2x 2x 3x 5x 11
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3x 3x 3x 5 = 4860
Therefore, the value for common factors is 4860.
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 = 89248477309200/(1x4860)
LCM = 89248477309200/4860
LCM = 18363884220
Thus, we can understand that the LCM of 797,405,431,660,972 is 18363884220.
