Find LCM of 986,646,936,168 with Prime Factorization
2 | 986, 646, 936, 168 |
2 | 493, 323, 468, 84 |
2 | 493, 323, 234, 42 |
3 | 493, 323, 117, 21 |
17 | 493, 323, 39, 7 |
29, 19, 39, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 29 x 19 x 39 x 7 = 61372584
Therefore, the lowest common multiple of 986,646,936,168 is 61372584.
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.
986 x 646 x 936 x 168 = 100160057088
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
646 : 1, 2, 17, 19, 34, 38, 323, 646
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,646,936,168, is 2.
Now, the common factors can be found like this.
986:2x 17x 29
646:2x 17x 19
936:2x 2x 2x 3x 3x 13
168:2x 2x 2x 3x 7
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 3x 17 = 816
Therefore, the value for common factors is 816.
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 = 100160057088/(2x816)
LCM = 100160057088/1632
LCM = 61372584
Thus, we can understand that the LCM of 986,646,936,168 is 61372584.
