Given numbers are 793,625,978,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,625,978,394 is 95490086250.
Find LCM of 793,625,978,394 with Prime Factorization
| 2 | 793, 625, 978, 394 |
| 793, 625, 489, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 793 x 625 x 489 x 197 = 95490086250
Therefore, the lowest common multiple of 793,625,978,394 is 95490086250.
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.
793 x 625 x 978 x 394 = 190980172500
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.
793 : 1, 13, 61, 793
625 : 1, 5, 25, 125, 625
978 : 1, 2, 3, 6, 163, 326, 489, 978
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,625,978,394, is 1.
Now, the common factors can be found like this.
793:13x 61
625:5x 5x 5x 5
978:2x 3x 163
394:2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 190980172500/(1x2)
LCM = 190980172500/2
LCM = 95490086250
Thus, we can understand that the LCM of 793,625,978,394 is 95490086250.
