Given numbers are 833,238,986,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 833,238,986,987 is 6812274.
Find LCM of 833,238,986,987 with Prime Factorization
| 2 | 833, 238, 986, 987 |
| 7 | 833, 119, 493, 987 |
| 17 | 17, 119, 493, 141 |
| 1, 7, 29, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 1 x 7 x 29 x 141 = 6812274
Therefore, the lowest common multiple of 833,238,986,987 is 6812274.
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.
833 x 238 x 986 x 987 = 192937224228
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.
833 : 1, 7, 17, 49, 119, 833
238 : 1, 2, 7, 14, 17, 34, 119, 238
986 : 1, 2, 17, 29, 34, 58, 493, 986
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,238,986,987, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
238:2x 7x 17
986:2x 17x 29
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 17x 17 = 28322
Therefore, the value for common factors is 28322.
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 = 192937224228/(1x28322)
LCM = 192937224228/28322
LCM = 6812274
Thus, we can understand that the LCM of 833,238,986,987 is 6812274.
