Find LCM of 867,181,420,697,287 with Prime Factorization
| 3 | 867, 181, 420, 697, 287 |
| 7 | 289, 181, 140, 697, 287 |
| 17 | 289, 181, 20, 697, 41 |
| 41 | 17, 181, 20, 41, 41 |
| 17, 181, 20, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 17 x 41 x 17 x 181 x 20 x 1 x 1 = 900760980
Therefore, the lowest common multiple of 867,181,420,697,287 is 900760980.
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.
867 x 181 x 420 x 697 x 287 = 13184438464260
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.
867 : 1, 3, 17, 51, 289, 867
181 : 1, 181
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
697 : 1, 17, 41, 697
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,181,420,697,287, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
181:181
420:2x 2x 3x 5x 7
697:17x 41
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 17x 41 = 14637
Therefore, the value for common factors is 14637.
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 = 13184438464260/(1x14637)
LCM = 13184438464260/14637
LCM = 900760980
Thus, we can understand that the LCM of 867,181,420,697,287 is 900760980.
