Find LCM of 485,872,665,161,988 with Prime Factorization
2 | 485, 872, 665, 161, 988 |
2 | 485, 436, 665, 161, 494 |
5 | 485, 218, 665, 161, 247 |
7 | 97, 218, 133, 161, 247 |
19 | 97, 218, 19, 23, 247 |
97, 218, 1, 23, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 97 x 218 x 1 x 23 x 13 = 16818259640
Therefore, the lowest common multiple of 485,872,665,161,988 is 16818259640.
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.
485 x 872 x 665 x 161 x 988 = 44736570642400
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.
485 : 1, 5, 97, 485
872 : 1, 2, 4, 8, 109, 218, 436, 872
665 : 1, 5, 7, 19, 35, 95, 133, 665
161 : 1, 7, 23, 161
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,872,665,161,988, is 1.
Now, the common factors can be found like this.
485:5x 97
872:2x 2x 2x 109
665:5x 7x 19
161:7x 23
988:2x 2x 13x 19
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 5x 7x 19 = 2660
Therefore, the value for common factors is 2660.
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 = 44736570642400/(1x2660)
LCM = 44736570642400/2660
LCM = 16818259640
Thus, we can understand that the LCM of 485,872,665,161,988 is 16818259640.
