Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 661 x 457 x 1 x 4 x 83 = 48138990720
Therefore, the lowest common multiple of 661,914,480,640,249 is 48138990720.
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.
661 x 914 x 480 x 640 x 249 = 46213431091200
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.
661 : 1, 661
914 : 1, 2, 457, 914
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,914,480,640,249, is 1.
Now, the common factors can be found like this.
661:661
914:2x 457
480:2x 2x 2x 2x 2x 3x 5
640:2x 2x 2x 2x 2x 2x 2x 5
249:3x 83
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 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 46213431091200/(1x960)
LCM = 46213431091200/960
LCM = 48138990720
Thus, we can understand that the LCM of 661,914,480,640,249 is 48138990720.
