Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 13 x 1 x 953 x 4 x 3 x 1 = 124881120
Therefore, the lowest common multiple of 728,953,480,360,455 is 124881120.
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.
728 x 953 x 480 x 360 x 455 = 54548073216000
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
953 : 1, 953
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
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,953,480,360,455, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
953:953
480:2x 2x 2x 2x 2x 3x 5
360:2x 2x 2x 3x 3x 5
455:5x 7x 13
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 5x 5x 7x 13 = 436800
Therefore, the value for common factors is 436800.
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 = 54548073216000/(1x436800)
LCM = 54548073216000/436800
LCM = 124881120
Thus, we can understand that the LCM of 728,953,480,360,455 is 124881120.
