| 19 | 19, 797, 157, 19, 3 |
| 1, 797, 157, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 19 x 1 x 797 x 157 x 1 x 3 = 8986764780
Therefore, the lowest common multiple of 855,797,628,665,756 is 8986764780.
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.
855 x 797 x 628 x 665 x 756 = 215143148833200
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
797 : 1, 797
628 : 1, 2, 4, 157, 314, 628
665 : 1, 5, 7, 19, 35, 95, 133, 665
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,797,628,665,756, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
797:797
628:2x 2x 157
665:5x 7x 19
756:2x 2x 3x 3x 3x 7
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 3x 3x 5x 7x 19 = 23940
Therefore, the value for common factors is 23940.
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 = 215143148833200/(1x23940)
LCM = 215143148833200/23940
LCM = 8986764780
Thus, we can understand that the LCM of 855,797,628,665,756 is 8986764780.
