Given numbers are 170,545,999,680,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,545,999,680,742 is 27471021480.
Find LCM of 170,545,999,680,742 with Prime Factorization
| 2 | 170, 545, 999, 680, 742 |
| 5 | 85, 545, 999, 340, 371 |
| 17 | 17, 109, 999, 68, 371 |
| 1, 109, 999, 4, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 1 x 109 x 999 x 4 x 371 = 27471021480
Therefore, the lowest common multiple of 170,545,999,680,742 is 27471021480.
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.
170 x 545 x 999 x 680 x 742 = 46700736516000
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
545 : 1, 5, 109, 545
999 : 1, 3, 9, 27, 37, 111, 333, 999
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,545,999,680,742, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
545:5x 109
999:3x 3x 3x 37
680:2x 2x 2x 5x 17
742:2x 7x 53
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 5x 5x 17 = 1700
Therefore, the value for common factors is 1700.
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 = 46700736516000/(1x1700)
LCM = 46700736516000/1700
LCM = 27471021480
Thus, we can understand that the LCM of 170,545,999,680,742 is 27471021480.
