Given numbers are 248,342,540,750,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,342,540,750,660 is 174933000.
Find LCM of 248,342,540,750,660 with Prime Factorization
| 2 | 248, 342, 540, 750, 660 |
| 2 | 124, 171, 270, 375, 330 |
| 3 | 62, 171, 135, 375, 165 |
| 3 | 62, 57, 45, 125, 55 |
| 5 | 62, 19, 15, 125, 55 |
| 62, 19, 3, 25, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 62 x 19 x 3 x 25 x 11 = 174933000
Therefore, the lowest common multiple of 248,342,540,750,660 is 174933000.
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.
248 x 342 x 540 x 750 x 660 = 22671316800000
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,342,540,750,660, is 2.
Now, the common factors can be found like this.
248:2x 2x 2x 31
342:2x 3x 3x 19
540:2x 2x 3x 3x 3x 5
750:2x 3x 5x 5x 5
660:2x 2x 3x 5x 11
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 3x 3x 3x 3x 5x 5 = 64800
Therefore, the value for common factors is 64800.
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 = 22671316800000/(2x64800)
LCM = 22671316800000/129600
LCM = 174933000
Thus, we can understand that the LCM of 248,342,540,750,660 is 174933000.
