Given numbers are 392,142,292,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,142,292,923 is 26412568.
Find LCM of 392,142,292,923 with Prime Factorization
| 2 | 392, 142, 292, 923 |
| 2 | 196, 71, 146, 923 |
| 71 | 98, 71, 73, 923 |
| 98, 1, 73, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 98 x 1 x 73 x 13 = 26412568
Therefore, the lowest common multiple of 392,142,292,923 is 26412568.
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.
392 x 142 x 292 x 923 = 15002338624
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
142 : 1, 2, 71, 142
292 : 1, 2, 4, 73, 146, 292
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,142,292,923, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
142:2x 71
292:2x 2x 73
923:13x 71
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 71 = 568
Therefore, the value for common factors is 568.
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 = 15002338624/(1x568)
LCM = 15002338624/568
LCM = 26412568
Thus, we can understand that the LCM of 392,142,292,923 is 26412568.
