Given numbers are 477,450,821,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 477,450,821,720 is 156646800.
Find LCM of 477,450,821,720 with Prime Factorization
| 2 | 477, 450, 821, 720 |
| 3 | 477, 225, 821, 360 |
| 3 | 159, 75, 821, 120 |
| 5 | 53, 25, 821, 40 |
| 53, 5, 821, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 53 x 5 x 821 x 8 = 156646800
Therefore, the lowest common multiple of 477,450,821,720 is 156646800.
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.
477 x 450 x 821 x 720 = 126883908000
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.
477 : 1, 3, 9, 53, 159, 477
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
821 : 1, 821
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,450,821,720, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
450:2x 3x 3x 5x 5
821:821
720:2x 2x 2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 126883908000/(1x810)
LCM = 126883908000/810
LCM = 156646800
Thus, we can understand that the LCM of 477,450,821,720 is 156646800.
