| 3 | 781, 27, 21, 17, 19 |
| 781, 9, 7, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 781 x 9 x 7 x 17 x 19 = 4577059872
Therefore, the lowest common multiple of 781,648,126,544,608 is 4577059872.
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.
781 x 648 x 126 x 544 x 608 = 21091091890176
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.
781 : 1, 11, 71, 781
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,648,126,544,608, is 1.
Now, the common factors can be found like this.
781:11x 71
648:2x 2x 2x 3x 3x 3x 3
126:2x 3x 3x 7
544:2x 2x 2x 2x 2x 17
608:2x 2x 2x 2x 2x 19
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 2x 2x 2x 3x 3 = 4608
Therefore, the value for common factors is 4608.
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 = 21091091890176/(1x4608)
LCM = 21091091890176/4608
LCM = 4577059872
Thus, we can understand that the LCM of 781,648,126,544,608 is 4577059872.
