Find LCM of 774,986,988,905,342 with Prime Factorization
2 | 774, 986, 988, 905, 342 |
3 | 387, 493, 494, 905, 171 |
3 | 129, 493, 494, 905, 57 |
19 | 43, 493, 494, 905, 19 |
43, 493, 26, 905, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 43 x 493 x 26 x 905 x 1 = 170593864740
Therefore, the lowest common multiple of 774,986,988,905,342 is 170593864740.
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.
774 x 986 x 988 x 905 x 342 = 233372406964320
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
986 : 1, 2, 17, 29, 34, 58, 493, 986
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
905 : 1, 5, 181, 905
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,986,988,905,342, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
986:2x 17x 29
988:2x 2x 13x 19
905:5x 181
342:2x 3x 3x 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 2x 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 233372406964320/(1x1368)
LCM = 233372406964320/1368
LCM = 170593864740
Thus, we can understand that the LCM of 774,986,988,905,342 is 170593864740.
