Given numbers are 368,170,360,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 368,170,360,988 is 69535440.
Find LCM of 368,170,360,988 with Prime Factorization
| 2 | 368, 170, 360, 988 |
| 2 | 184, 85, 180, 494 |
| 2 | 92, 85, 90, 247 |
| 5 | 46, 85, 45, 247 |
| 46, 17, 9, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 46 x 17 x 9 x 247 = 69535440
Therefore, the lowest common multiple of 368,170,360,988 is 69535440.
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.
368 x 170 x 360 x 988 = 22251340800
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
170 : 1, 2, 5, 10, 17, 34, 85, 170
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,170,360,988, is 2.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
170:2x 5x 17
360:2x 2x 2x 3x 3x 5
988:2x 2x 13x 19
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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 22251340800/(2x160)
LCM = 22251340800/320
LCM = 69535440
Thus, we can understand that the LCM of 368,170,360,988 is 69535440.
