Given numbers are 186,840,336,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,840,336,221 is 11509680.
Find LCM of 186,840,336,221 with Prime Factorization
| 2 | 186, 840, 336, 221 |
| 2 | 93, 420, 168, 221 |
| 2 | 93, 210, 84, 221 |
| 3 | 93, 105, 42, 221 |
| 7 | 31, 35, 14, 221 |
| 31, 5, 2, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 31 x 5 x 2 x 221 = 11509680
Therefore, the lowest common multiple of 186,840,336,221 is 11509680.
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.
186 x 840 x 336 x 221 = 11601757440
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,840,336,221, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
840:2x 2x 2x 3x 5x 7
336:2x 2x 2x 2x 3x 7
221:13x 17
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 11601757440/(1x1008)
LCM = 11601757440/1008
LCM = 11509680
Thus, we can understand that the LCM of 186,840,336,221 is 11509680.
