Given numbers are 483,540,420,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 483,540,420,676 is 14692860.
Find LCM of 483,540,420,676 with Prime Factorization
| 2 | 483, 540, 420, 676 |
| 2 | 483, 270, 210, 338 |
| 3 | 483, 135, 105, 169 |
| 5 | 161, 45, 35, 169 |
| 7 | 161, 9, 7, 169 |
| 23, 9, 1, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 23 x 9 x 1 x 169 = 14692860
Therefore, the lowest common multiple of 483,540,420,676 is 14692860.
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.
483 x 540 x 420 x 676 = 74052014400
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.
483 : 1, 3, 7, 21, 23, 69, 161, 483
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
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 483,540,420,676, is 1.
Now, the common factors can be found like this.
483:3x 7x 23
540:2x 2x 3x 3x 3x 5
420:2x 2x 3x 5x 7
676:2x 2x 13x 13
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 3x 3x 5x 7 = 5040
Therefore, the value for common factors is 5040.
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 = 74052014400/(1x5040)
LCM = 74052014400/5040
LCM = 14692860
Thus, we can understand that the LCM of 483,540,420,676 is 14692860.
