HCF of 12, 15 and 21 can be represented as HCF of (HCF of 12, 15) and 21. HCF(12, 15, 21) can be thus calculated by first finding HCF(12, 15) using long division and thereafter using this result with 21 to perform long division again. Step 1:Divide15 (larger number) by 12 ...
At last, the HCF lives of the LC4 specimens are predicted by three different methods. It is found that there exists a relatively large error in the predicted results by the CDM finite element method. For the ANN model trained only with the experimental data, the accuracy of the predicted ...
