Find the HCF as a product of prime numbers

Question 1:

$A = 2^{2} \times 5^{2} B = 2^{3} \times 5$

$HCF = 2^{2} \times 5$

Question 2:

$A = 2 \times 5^{2} B = 2^{2} \times 3 \times 5$

$HCF = 2 \times 5$

Question 3:

$A = 2 \times 5^{2} B = 2^{2} \times 3^{2} \times 5$

$HCF = 2 \times 5$

Question 4:

$A = 5^{3} B = 2^{2} \times 5^{2}$

$HCF = 5^{2}$
