Find LCM of 209,908,440,679,728 with Prime Factorization
| 2 | 209, 908, 440, 679, 728 |
| 2 | 209, 454, 220, 679, 364 |
| 2 | 209, 227, 110, 679, 182 |
| 7 | 209, 227, 55, 679, 91 |
| 11 | 209, 227, 55, 97, 13 |
| 19, 227, 5, 97, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 19 x 227 x 5 x 97 x 13 = 16751174440
Therefore, the lowest common multiple of 209,908,440,679,728 is 16751174440.
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.
209 x 908 x 440 x 679 x 728 = 41274893820160
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.
209 : 1, 11, 19, 209
908 : 1, 2, 4, 227, 454, 908
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
679 : 1, 7, 97, 679
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,908,440,679,728, is 1.
Now, the common factors can be found like this.
209:11x 19
908:2x 2x 227
440:2x 2x 2x 5x 11
679:7x 97
728:2x 2x 2x 7x 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 7x 11 = 2464
Therefore, the value for common factors is 2464.
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 = 41274893820160/(1x2464)
LCM = 41274893820160/2464
LCM = 16751174440
Thus, we can understand that the LCM of 209,908,440,679,728 is 16751174440.
