The LCM of 266,781,363,168 is 27422472.
Find LCM of 266,781,363,168 with Prime Factorization
| 2 | 266, 781, 363, 168 |
| 3 | 133, 781, 363, 84 |
| 7 | 133, 781, 121, 28 |
| 11 | 19, 781, 121, 4 |
| 19, 71, 11, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 19 x 71 x 11 x 4 = 27422472
Therefore, the lowest common multiple of 266,781,363,168 is 27422472.
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.
266 x 781 x 363 x 168 = 12669182064
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.
266 : 1, 2, 7, 14, 19, 38, 133, 266
781 : 1, 11, 71, 781
363 : 1, 3, 11, 33, 121, 363
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,781,363,168, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
781:11x 71
363:3x 11x 11
168:2x 2x 2x 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 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 12669182064/(1x462)
LCM = 12669182064/462
LCM = 27422472
Thus, we can understand that the LCM of 266,781,363,168 is 27422472.
