Find LCM of 181,988,646,866,312 with Prime Factorization
2 | 181, 988, 646, 866, 312 |
2 | 181, 494, 323, 433, 156 |
13 | 181, 247, 323, 433, 78 |
19 | 181, 19, 323, 433, 6 |
181, 1, 17, 433, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 181 x 1 x 17 x 433 x 6 = 7898117448
Therefore, the lowest common multiple of 181,988,646,866,312 is 7898117448.
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.
181 x 988 x 646 x 866 x 312 = 31213360154496
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.
181 : 1, 181
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
646 : 1, 2, 17, 19, 34, 38, 323, 646
866 : 1, 2, 433, 866
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,988,646,866,312, is 1.
Now, the common factors can be found like this.
181:181
988:2x 2x 13x 19
646:2x 17x 19
866:2x 433
312:2x 2x 2x 3x 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 13x 19 = 3952
Therefore, the value for common factors is 3952.
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 = 31213360154496/(1x3952)
LCM = 31213360154496/3952
LCM = 7898117448
Thus, we can understand that the LCM of 181,988,646,866,312 is 7898117448.
