Given numbers are 985,866,320,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,866,320,749 is 20444943680.
Find LCM of 985,866,320,749 with Prime Factorization
| 2 | 985, 866, 320, 749 |
| 5 | 985, 433, 160, 749 |
| 197, 433, 32, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 197 x 433 x 32 x 749 = 20444943680
Therefore, the lowest common multiple of 985,866,320,749 is 20444943680.
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.
985 x 866 x 320 x 749 = 204449436800
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.
985 : 1, 5, 197, 985
866 : 1, 2, 433, 866
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,866,320,749, is 1.
Now, the common factors can be found like this.
985:5x 197
866:2x 433
320:2x 2x 2x 2x 2x 2x 5
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 204449436800/(1x10)
LCM = 204449436800/10
LCM = 20444943680
Thus, we can understand that the LCM of 985,866,320,749 is 20444943680.
