Given numbers are 421,814,777,833
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,814,777,833 is 856392306.
Find LCM of 421,814,777,833 with Prime Factorization
| 7 | 421, 814, 777, 833 |
| 37 | 421, 814, 111, 119 |
| 421, 22, 3, 119 |
Multiply the prime numbers at the bottom and the left side.
7 x 37 x 421 x 22 x 3 x 119 = 856392306
Therefore, the lowest common multiple of 421,814,777,833 is 856392306.
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.
421 x 814 x 777 x 833 = 221805607254
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.
421 : 1, 421
814 : 1, 2, 11, 22, 37, 74, 407, 814
777 : 1, 3, 7, 21, 37, 111, 259, 777
833 : 1, 7, 17, 49, 119, 833
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,814,777,833, is 1.
Now, the common factors can be found like this.
421:421
814:2x 11x 37
777:3x 7x 37
833:7x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 37 = 259
Therefore, the value for common factors is 259.
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 = 221805607254/(1x259)
LCM = 221805607254/259
LCM = 856392306
Thus, we can understand that the LCM of 421,814,777,833 is 856392306.
