Given numbers are 889,803,686,461,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,803,686,461,165 is 483766249890.
Find LCM of 889,803,686,461,165 with Prime Factorization
| 7 | 889, 803, 686, 461, 165 |
| 11 | 127, 803, 98, 461, 165 |
| 127, 73, 98, 461, 15 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 127 x 73 x 98 x 461 x 15 = 483766249890
Therefore, the lowest common multiple of 889,803,686,461,165 is 483766249890.
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.
889 x 803 x 686 x 461 x 165 = 37250001241530
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.
889 : 1, 7, 127, 889
803 : 1, 11, 73, 803
686 : 1, 2, 7, 14, 49, 98, 343, 686
461 : 1, 461
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,803,686,461,165, is 1.
Now, the common factors can be found like this.
889:7x 127
803:11x 73
686:2x 7x 7x 7
461:461
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11 = 77
Therefore, the value for common factors is 77.
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 = 37250001241530/(1x77)
LCM = 37250001241530/77
LCM = 483766249890
Thus, we can understand that the LCM of 889,803,686,461,165 is 483766249890.
