Given numbers are 171,861,528,431,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,861,528,431,170 is 316436717520.
Find LCM of 171,861,528,431,170 with Prime Factorization
| 2 | 171, 861, 528, 431, 170 |
| 3 | 171, 861, 264, 431, 85 |
| 57, 287, 88, 431, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 57 x 287 x 88 x 431 x 85 = 316436717520
Therefore, the lowest common multiple of 171,861,528,431,170 is 316436717520.
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.
171 x 861 x 528 x 431 x 170 = 5695860915360
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.
171 : 1, 3, 9, 19, 57, 171
861 : 1, 3, 7, 21, 41, 123, 287, 861
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
431 : 1, 431
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,861,528,431,170, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
861:3x 7x 41
528:2x 2x 2x 2x 3x 11
431:431
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 5695860915360/(1x18)
LCM = 5695860915360/18
LCM = 316436717520
Thus, we can understand that the LCM of 171,861,528,431,170 is 316436717520.
