Given numbers are 988,836,950,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,836,950,938 is 127427300.
Find LCM of 988,836,950,938 with Prime Factorization
| 2 | 988, 836, 950, 938 |
| 2 | 494, 418, 475, 469 |
| 19 | 247, 209, 475, 469 |
| 13, 11, 25, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 13 x 11 x 25 x 469 = 127427300
Therefore, the lowest common multiple of 988,836,950,938 is 127427300.
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.
988 x 836 x 950 x 938 = 736020084800
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
938 : 1, 2, 7, 14, 67, 134, 469, 938
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,836,950,938, is 2.
Now, the common factors can be found like this.
988:2x 2x 13x 19
836:2x 2x 11x 19
950:2x 5x 5x 19
938:2x 7x 67
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 19x 19 = 2888
Therefore, the value for common factors is 2888.
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 = 736020084800/(2x2888)
LCM = 736020084800/5776
LCM = 127427300
Thus, we can understand that the LCM of 988,836,950,938 is 127427300.
