Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 17 x 43 x 29 x 1 x 407 x 2 = 4969723968
Therefore, the lowest common multiple of 731,493,576,407,288 is 4969723968.
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 493 x 576 x 407 x 288 = 24331768547328
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
493 : 1, 17, 29, 493
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
407 : 1, 11, 37, 407
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,493,576,407,288, is 1.
Now, the common factors can be found like this.
731:17x 43
493:17x 29
576:2x 2x 2x 2x 2x 2x 3x 3
407:11x 37
288:2x 2x 2x 2x 2x 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 2x 2x 2x 3x 3x 17 = 4896
Therefore, the value for common factors is 4896.
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 = 24331768547328/(1x4896)
LCM = 24331768547328/4896
LCM = 4969723968
Thus, we can understand that the LCM of 731,493,576,407,288 is 4969723968.
