23 | 97, 23, 35, 92, 229 |
97, 1, 35, 4, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 23 x 97 x 1 x 35 x 4 x 229 = 15449585760
Therefore, the lowest common multiple of 776,621,945,736,687 is 15449585760.
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.
776 x 621 x 945 x 736 x 687 = 230260626167040
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.
776 : 1, 2, 4, 8, 97, 194, 388, 776
621 : 1, 3, 9, 23, 27, 69, 207, 621
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,621,945,736,687, is 1.
Now, the common factors can be found like this.
776:2x 2x 2x 97
621:3x 3x 3x 23
945:3x 3x 3x 5x 7
736:2x 2x 2x 2x 2x 23
687:3x 229
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 3x 3x 3x 3x 23 = 14904
Therefore, the value for common factors is 14904.
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 = 230260626167040/(1x14904)
LCM = 230260626167040/14904
LCM = 15449585760
Thus, we can understand that the LCM of 776,621,945,736,687 is 15449585760.
