Given numbers are 495,175,620,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 495,175,620,171 is 40817700.
Find LCM of 495,175,620,171 with Prime Factorization
| 3 | 495, 175, 620, 171 |
| 3 | 165, 175, 620, 57 |
| 5 | 55, 175, 620, 19 |
| 11, 35, 124, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 35 x 124 x 19 = 40817700
Therefore, the lowest common multiple of 495,175,620,171 is 40817700.
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.
495 x 175 x 620 x 171 = 9183982500
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
175 : 1, 5, 7, 25, 35, 175
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,175,620,171, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
175:5x 5x 7
620:2x 2x 5x 31
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 9183982500/(1x225)
LCM = 9183982500/225
LCM = 40817700
Thus, we can understand that the LCM of 495,175,620,171 is 40817700.
