Given numbers are 824,574,824,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,574,824,765 is 180913320.
Find LCM of 824,574,824,765 with Prime Factorization
| 2 | 824, 574, 824, 765 |
| 2 | 412, 287, 412, 765 |
| 2 | 206, 287, 206, 765 |
| 103 | 103, 287, 103, 765 |
| 1, 287, 1, 765 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 103 x 1 x 287 x 1 x 765 = 180913320
Therefore, the lowest common multiple of 824,574,824,765 is 180913320.
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.
824 x 574 x 824 x 765 = 298145151360
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
574 : 1, 2, 7, 14, 41, 82, 287, 574
824 : 1, 2, 4, 8, 103, 206, 412, 824
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,574,824,765, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
574:2x 7x 41
824:2x 2x 2x 103
765:3x 3x 5x 17
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 103 = 1648
Therefore, the value for common factors is 1648.
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 = 298145151360/(1x1648)
LCM = 298145151360/1648
LCM = 180913320
Thus, we can understand that the LCM of 824,574,824,765 is 180913320.
