Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 11 x 1 x 19 x 4 x 21 x 1 = 15800400
Therefore, the lowest common multiple of 275,418,400,756,990 is 15800400.
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.
275 x 418 x 400 x 756 x 990 = 34413271200000
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.
275 : 1, 5, 11, 25, 55, 275
418 : 1, 2, 11, 19, 22, 38, 209, 418
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 275,418,400,756,990, is 1.
Now, the common factors can be found like this.
275:5x 5x 11
418:2x 11x 19
400:2x 2x 2x 2x 5x 5
756:2x 2x 3x 3x 3x 7
990:2x 3x 3x 5x 11
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 3x 3x 5x 5x 5x 11x 11 = 2178000
Therefore, the value for common factors is 2178000.
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 = 34413271200000/(1x2178000)
LCM = 34413271200000/2178000
LCM = 15800400
Thus, we can understand that the LCM of 275,418,400,756,990 is 15800400.
