Find LCM of 291,281,336,880,860 with Prime Factorization
| 2 | 291, 281, 336, 880, 860 |
| 2 | 291, 281, 168, 440, 430 |
| 2 | 291, 281, 84, 220, 215 |
| 2 | 291, 281, 42, 110, 215 |
| 3 | 291, 281, 21, 55, 215 |
| 5 | 97, 281, 7, 55, 215 |
| 97, 281, 7, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 97 x 281 x 7 x 11 x 43 = 21659502480
Therefore, the lowest common multiple of 291,281,336,880,860 is 21659502480.
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.
291 x 281 x 336 x 880 x 860 = 20793122380800
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.
291 : 1, 3, 97, 291
281 : 1, 281
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,281,336,880,860, is 1.
Now, the common factors can be found like this.
291:3x 97
281:281
336:2x 2x 2x 2x 3x 7
880:2x 2x 2x 2x 5x 11
860:2x 2x 5x 43
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 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 20793122380800/(1x960)
LCM = 20793122380800/960
LCM = 21659502480
Thus, we can understand that the LCM of 291,281,336,880,860 is 21659502480.
