Given numbers are 308,540,727,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,540,727,636 is 1602118980.
Find LCM of 308,540,727,636 with Prime Factorization
| 2 | 308, 540, 727, 636 |
| 2 | 154, 270, 727, 318 |
| 3 | 77, 135, 727, 159 |
| 77, 45, 727, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 77 x 45 x 727 x 53 = 1602118980
Therefore, the lowest common multiple of 308,540,727,636 is 1602118980.
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.
308 x 540 x 727 x 636 = 76901711040
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
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
727 : 1, 727
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,540,727,636, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
540:2x 2x 3x 3x 3x 5
727:727
636:2x 2x 3x 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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 76901711040/(1x48)
LCM = 76901711040/48
LCM = 1602118980
Thus, we can understand that the LCM of 308,540,727,636 is 1602118980.
