The LCM of 983,156,988,722 is 55358628.
Find LCM of 983,156,988,722 with Prime Factorization
| 2 | 983, 156, 988, 722 |
| 2 | 983, 78, 494, 361 |
| 13 | 983, 39, 247, 361 |
| 19 | 983, 3, 19, 361 |
| 983, 3, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 983 x 3 x 1 x 19 = 55358628
Therefore, the lowest common multiple of 983,156,988,722 is 55358628.
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.
983 x 156 x 988 x 722 = 109388648928
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.
983 : 1, 983
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,156,988,722, is 1.
Now, the common factors can be found like this.
983:983
156:2x 2x 3x 13
988:2x 2x 13x 19
722:2x 19x 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 2x 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 109388648928/(1x1976)
LCM = 109388648928/1976
LCM = 55358628
Thus, we can understand that the LCM of 983,156,988,722 is 55358628.
