The LCM of 629,342,774,172 is 18500148.
Find LCM of 629,342,774,172 with Prime Factorization
| 2 | 629, 342, 774, 172 |
| 3 | 629, 171, 387, 86 |
| 3 | 629, 57, 129, 86 |
| 43 | 629, 19, 43, 86 |
| 629, 19, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 43 x 629 x 19 x 1 x 2 = 18500148
Therefore, the lowest common multiple of 629,342,774,172 is 18500148.
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.
629 x 342 x 774 x 172 = 28638229104
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.
629 : 1, 17, 37, 629
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,342,774,172, is 1.
Now, the common factors can be found like this.
629:17x 37
342:2x 3x 3x 19
774:2x 3x 3x 43
172:2x 2x 43
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 43 = 1548
Therefore, the value for common factors is 1548.
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 = 28638229104/(1x1548)
LCM = 28638229104/1548
LCM = 18500148
Thus, we can understand that the LCM of 629,342,774,172 is 18500148.
