The LCM of 168,774,946,126 is 238392.
Find LCM of 168,774,946,126 with Prime Factorization
| 2 | 168, 774, 946, 126 |
| 3 | 84, 387, 473, 63 |
| 3 | 28, 129, 473, 21 |
| 7 | 28, 43, 473, 7 |
| 43 | 4, 43, 473, 1 |
| 4, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 43 x 4 x 1 x 11 x 1 = 238392
Therefore, the lowest common multiple of 168,774,946,126 is 238392.
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 774 x 946 x 126 = 15499294272
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
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
946 : 1, 2, 11, 22, 43, 86, 473, 946
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,774,946,126, is 2.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
774:2x 3x 3x 43
946:2x 11x 43
126:2x 3x 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 3x 3x 3x 7x 43 = 32508
Therefore, the value for common factors is 32508.
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 = 15499294272/(2x32508)
LCM = 15499294272/65016
LCM = 238392
Thus, we can understand that the LCM of 168,774,946,126 is 238392.
