Given numbers are 159,492,391,170,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,492,391,170,474 is 4027307820.
Find LCM of 159,492,391,170,474 with Prime Factorization
| 2 | 159, 492, 391, 170, 474 |
| 3 | 159, 246, 391, 85, 237 |
| 17 | 53, 82, 391, 85, 79 |
| 53, 82, 23, 5, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 53 x 82 x 23 x 5 x 79 = 4027307820
Therefore, the lowest common multiple of 159,492,391,170,474 is 4027307820.
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.
159 x 492 x 391 x 170 x 474 = 2464712385840
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.
159 : 1, 3, 53, 159
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
391 : 1, 17, 23, 391
170 : 1, 2, 5, 10, 17, 34, 85, 170
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,492,391,170,474, is 1.
Now, the common factors can be found like this.
159:3x 53
492:2x 2x 3x 41
391:17x 23
170:2x 5x 17
474:2x 3x 79
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 17 = 612
Therefore, the value for common factors is 612.
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 = 2464712385840/(1x612)
LCM = 2464712385840/612
LCM = 4027307820
Thus, we can understand that the LCM of 159,492,391,170,474 is 4027307820.
