Concept: The H.C.F of 2, 3 and 5 is 1.Write down each of components 2, 3, and 5 first. Now we should think about the shared characteristics of 2, 3, and 5. We need to identify the 2, 3, and 5 factors with the highest common factor. The H.C.F of 2, 3, and 5 is determined by finding their highest common factor. We can determine the H.C.F. of 2, 3, and 5 in this method.
We need to comprehend the meaning of H.C.F. before we can answer the question. Each and every factor of the three numbers must be mentioned in order to determine the H.C.F. All three numbers' common factors must now be written down. We need to identify the common factor that is most prevalent among the others. The
We are given the numbers 2, 3, and 5 in the inquiry. We must now determine the HCF of 2,3,5.
2=2×1....(1) 
3=3×1....(2) 
5=5×1....(3) 
The factors of 2, 3, and 5 can be obtained from equations (1) , (2) , and (3) .
2, 3, and 5 share the same factor, which is 1.
