Find LCM of 697,728,455,874,164 with Prime Factorization
| 2 | 697, 728, 455, 874, 164 |
| 2 | 697, 364, 455, 437, 82 |
| 7 | 697, 182, 455, 437, 41 |
| 13 | 697, 26, 65, 437, 41 |
| 41 | 697, 2, 5, 437, 41 |
| 17, 2, 5, 437, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 41 x 17 x 2 x 5 x 437 x 1 = 1108703960
Therefore, the lowest common multiple of 697,728,455,874,164 is 1108703960.
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.
697 x 728 x 455 x 874 x 164 = 33092595798080
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.
697 : 1, 17, 41, 697
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
455 : 1, 5, 7, 13, 35, 65, 91, 455
874 : 1, 2, 19, 23, 38, 46, 437, 874
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,728,455,874,164, is 1.
Now, the common factors can be found like this.
697:17x 41
728:2x 2x 2x 7x 13
455:5x 7x 13
874:2x 19x 23
164:2x 2x 41
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 7x 13x 41 = 29848
Therefore, the value for common factors is 29848.
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 = 33092595798080/(1x29848)
LCM = 33092595798080/29848
LCM = 1108703960
Thus, we can understand that the LCM of 697,728,455,874,164 is 1108703960.
