Given numbers are 836,690,802,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,690,802,798 is 809594940.
Find LCM of 836,690,802,798 with Prime Factorization
| 2 | 836, 690, 802, 798 |
| 3 | 418, 345, 401, 399 |
| 19 | 418, 115, 401, 133 |
| 22, 115, 401, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 22 x 115 x 401 x 7 = 809594940
Therefore, the lowest common multiple of 836,690,802,798 is 809594940.
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.
836 x 690 x 802 x 798 = 369175292640
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
802 : 1, 2, 401, 802
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,690,802,798, is 2.
Now, the common factors can be found like this.
836:2x 2x 11x 19
690:2x 3x 5x 23
802:2x 401
798:2x 3x 7x 19
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 369175292640/(2x228)
LCM = 369175292640/456
LCM = 809594940
Thus, we can understand that the LCM of 836,690,802,798 is 809594940.
