Given numbers are 939,911,639,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,911,639,761 is 138659052897.
Find LCM of 939,911,639,761 with Prime Factorization
| 3 | 939, 911, 639, 761 |
| 313, 911, 213, 761 |
Multiply the prime numbers at the bottom and the left side.
3 x 313 x 911 x 213 x 761 = 138659052897
Therefore, the lowest common multiple of 939,911,639,761 is 138659052897.
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.
939 x 911 x 639 x 761 = 415977158691
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.
939 : 1, 3, 313, 939
911 : 1, 911
639 : 1, 3, 9, 71, 213, 639
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,911,639,761, is 1.
Now, the common factors can be found like this.
939:3x 313
911:911
639:3x 3x 71
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 415977158691/(1x3)
LCM = 415977158691/3
LCM = 138659052897
Thus, we can understand that the LCM of 939,911,639,761 is 138659052897.
