Find LCM of 266,420,197,988,936 with Prime Factorization
| 2 | 266, 420, 197, 988, 936 |
| 2 | 133, 210, 197, 494, 468 |
| 3 | 133, 105, 197, 247, 234 |
| 7 | 133, 35, 197, 247, 78 |
| 13 | 19, 5, 197, 247, 78 |
| 19 | 19, 5, 197, 19, 6 |
| 1, 5, 197, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 19 x 1 x 5 x 197 x 1 x 6 = 122620680
Therefore, the lowest common multiple of 266,420,197,988,936 is 122620680.
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 420 x 197 x 988 x 936 = 20353070949120
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
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
197 : 1, 197
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,420,197,988,936, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
420:2x 2x 3x 5x 7
197:197
988:2x 2x 13x 19
936:2x 2x 2x 3x 3x 13
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 3x 7x 13x 19 = 165984
Therefore, the value for common factors is 165984.
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 = 20353070949120/(1x165984)
LCM = 20353070949120/165984
LCM = 122620680
Thus, we can understand that the LCM of 266,420,197,988,936 is 122620680.
