Given numbers are 746,393,394,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,393,394,442 is 12764090586.
Find LCM of 746,393,394,442 with Prime Factorization
2 | 746, 393, 394, 442 |
373, 393, 197, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 373 x 393 x 197 x 221 = 12764090586
Therefore, the lowest common multiple of 746,393,394,442 is 12764090586.
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.
746 x 393 x 394 x 442 = 51056362344
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.
746 : 1, 2, 373, 746
393 : 1, 3, 131, 393
394 : 1, 2, 197, 394
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,393,394,442, is 1.
Now, the common factors can be found like this.
746:2x 373
393:3x 131
394:2x 197
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 51056362344/(1x4)
LCM = 51056362344/4
LCM = 12764090586
Thus, we can understand that the LCM of 746,393,394,442 is 12764090586.
