Given numbers are 923,781,988,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,781,988,754 is 22377212.
Find LCM of 923,781,988,754 with Prime Factorization
| 2 | 923, 781, 988, 754 |
| 13 | 923, 781, 494, 377 |
| 71 | 71, 781, 38, 29 |
| 1, 11, 38, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 71 x 1 x 11 x 38 x 29 = 22377212
Therefore, the lowest common multiple of 923,781,988,754 is 22377212.
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.
923 x 781 x 988 x 754 = 537008333576
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.
923 : 1, 13, 71, 923
781 : 1, 11, 71, 781
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,781,988,754, is 1.
Now, the common factors can be found like this.
923:13x 71
781:11x 71
988:2x 2x 13x 19
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13x 71 = 23998
Therefore, the value for common factors is 23998.
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 = 537008333576/(1x23998)
LCM = 537008333576/23998
LCM = 22377212
Thus, we can understand that the LCM of 923,781,988,754 is 22377212.
