Answer 1

$\huge\underline\mathfrak{\pink{A}\green{N}\purple{S}\red{W}\orange{E}\blue{R}}$

Find the prime factorization of 196

196 = 2 × 2 × 7 × 7

Find the prime factorization of 256

256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

To find the HCF, multiply all the prime factors common to both numbers:

Therefore, HCF = 2 × 2

HCF = 4

Answer 2

Answer:

Find the prime factorization of 196

196 = 2 × 2 × 7 × 7

Find the prime factorization of 256

256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2

GCF = 4
