| 5 | 73, 15, 49, 50, 689 |
| 73, 3, 49, 10, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 73 x 3 x 49 x 10 x 689 = 53234344800
Therefore, the lowest common multiple of 657,540,784,800,689 is 53234344800.
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.
657 x 540 x 784 x 800 x 689 = 153314913024000
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.
657 : 1, 3, 9, 73, 219, 657
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,540,784,800,689, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
540:2x 2x 3x 3x 3x 5
784:2x 2x 2x 2x 7x 7
800:2x 2x 2x 2x 2x 5x 5
689:13x 53
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 3x 5 = 2880
Therefore, the value for common factors is 2880.
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 = 153314913024000/(1x2880)
LCM = 153314913024000/2880
LCM = 53234344800
Thus, we can understand that the LCM of 657,540,784,800,689 is 53234344800.
