Given numbers are 437,978,992,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,978,992,445 is 94332637920.
Find LCM of 437,978,992,445 with Prime Factorization
2 | 437, 978, 992, 445 |
437, 489, 496, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 437 x 489 x 496 x 445 = 94332637920
Therefore, the lowest common multiple of 437,978,992,445 is 94332637920.
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.
437 x 978 x 992 x 445 = 188665275840
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.
437 : 1, 19, 23, 437
978 : 1, 2, 3, 6, 163, 326, 489, 978
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,978,992,445, is 1.
Now, the common factors can be found like this.
437:19x 23
978:2x 3x 163
992:2x 2x 2x 2x 2x 31
445:5x 89
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 = 188665275840/(1x2)
LCM = 188665275840/2
LCM = 94332637920
Thus, we can understand that the LCM of 437,978,992,445 is 94332637920.
