HCF of 92 and 152 is
- ✓4
- B19
- C23
- D57
✓
Answer
Correct option: A.
4
(a)
Prime factorisation of $92=2 \times 2 \times 23$
Prime factorisation of $152=2 \times 2 \times 2 \times 19$
To find HCF, we multiply all the prime factors common to both number:
Therefore, $HCF =2 \times 2=4$
Prime factorisation of $92=2 \times 2 \times 23$
Prime factorisation of $152=2 \times 2 \times 2 \times 19$
To find HCF, we multiply all the prime factors common to both number:
Therefore, $HCF =2 \times 2=4$
