The LCM of 156,618,874,988 is 7021716.
Find LCM of 156,618,874,988 with Prime Factorization
| 2 | 156, 618, 874, 988 |
| 2 | 78, 309, 437, 494 |
| 3 | 39, 309, 437, 247 |
| 13 | 13, 103, 437, 247 |
| 19 | 1, 103, 437, 19 |
| 1, 103, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 1 x 103 x 23 x 1 = 7021716
Therefore, the lowest common multiple of 156,618,874,988 is 7021716.
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.
156 x 618 x 874 x 988 = 83249464896
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
618 : 1, 2, 3, 6, 103, 206, 309, 618
874 : 1, 2, 19, 23, 38, 46, 437, 874
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,618,874,988, is 2.
Now, the common factors can be found like this.
156:2x 2x 3x 13
618:2x 3x 103
874:2x 19x 23
988:2x 2x 13x 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 3x 13x 19 = 5928
Therefore, the value for common factors is 5928.
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 = 83249464896/(2x5928)
LCM = 83249464896/11856
LCM = 7021716
Thus, we can understand that the LCM of 156,618,874,988 is 7021716.
