Given numbers are 518,446,931,789,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,446,931,789,993 is 4012280256558.
Find LCM of 518,446,931,789,993 with Prime Factorization
2 | 518, 446, 931, 789, 993 |
3 | 259, 223, 931, 789, 993 |
7 | 259, 223, 931, 263, 331 |
37, 223, 133, 263, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 37 x 223 x 133 x 263 x 331 = 4012280256558
Therefore, the lowest common multiple of 518,446,931,789,993 is 4012280256558.
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.
518 x 446 x 931 x 789 x 993 = 168515770775436
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
446 : 1, 2, 223, 446
931 : 1, 7, 19, 49, 133, 931
789 : 1, 3, 263, 789
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,446,931,789,993, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
446:2x 223
931:7x 7x 19
789:3x 263
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 168515770775436/(1x42)
LCM = 168515770775436/42
LCM = 4012280256558
Thus, we can understand that the LCM of 518,446,931,789,993 is 4012280256558.
