Given numbers are 772,505,909,530
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,505,909,530 is 185963220.
Find LCM of 772,505,909,530 with Prime Factorization
| 2 | 772, 505, 909, 530 |
| 5 | 386, 505, 909, 265 |
| 101 | 386, 101, 909, 53 |
| 386, 1, 9, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 101 x 386 x 1 x 9 x 53 = 185963220
Therefore, the lowest common multiple of 772,505,909,530 is 185963220.
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.
772 x 505 x 909 x 530 = 187822852200
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.
772 : 1, 2, 4, 193, 386, 772
505 : 1, 5, 101, 505
909 : 1, 3, 9, 101, 303, 909
530 : 1, 2, 5, 10, 53, 106, 265, 530
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,505,909,530, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
505:5x 101
909:3x 3x 101
530:2x 5x 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 5x 101 = 1010
Therefore, the value for common factors is 1010.
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 = 187822852200/(1x1010)
LCM = 187822852200/1010
LCM = 185963220
Thus, we can understand that the LCM of 772,505,909,530 is 185963220.
