Given numbers are 168,637,163,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,637,163,494 is 47346936.
Find LCM of 168,637,163,494 with Prime Factorization
2 | 168, 637, 163, 494 |
7 | 84, 637, 163, 247 |
13 | 12, 91, 163, 247 |
12, 7, 163, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 12 x 7 x 163 x 19 = 47346936
Therefore, the lowest common multiple of 168,637,163,494 is 47346936.
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.
168 x 637 x 163 x 494 = 8617142352
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
637 : 1, 7, 13, 49, 91, 637
163 : 1, 163
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,637,163,494, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
637:7x 7x 13
163:163
494:2x 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 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 8617142352/(1x182)
LCM = 8617142352/182
LCM = 47346936
Thus, we can understand that the LCM of 168,637,163,494 is 47346936.
