Given numbers are 977,423,917,799,799
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,423,917,799,799 is 6442481619.
Find LCM of 977,423,917,799,799 with Prime Factorization
| 17 | 977, 423, 917, 799, 799 |
| 47 | 977, 423, 917, 47, 47 |
| 977, 9, 917, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
17 x 47 x 977 x 9 x 917 x 1 x 1 = 6442481619
Therefore, the lowest common multiple of 977,423,917,799,799 is 6442481619.
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.
977 x 423 x 917 x 799 x 799 = 241934512238307
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.
977 : 1, 977
423 : 1, 3, 9, 47, 141, 423
917 : 1, 7, 131, 917
799 : 1, 17, 47, 799
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,423,917,799,799, is 1.
Now, the common factors can be found like this.
977:977
423:3x 3x 47
917:7x 131
799:17x 47
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 47x 47 = 37553
Therefore, the value for common factors is 37553.
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 = 241934512238307/(1x37553)
LCM = 241934512238307/37553
LCM = 6442481619
Thus, we can understand that the LCM of 977,423,917,799,799 is 6442481619.
