If the HCF of 408 and 1032 is expressible in the form 1032 m – 408 × 5, find m.
Prime factors of 408: 2 × 2 × 2 x 3 × 17
Prime factors of 1032: 2 × 2 ×2 × 3 × 43
HCF of 408 and 1032 = 2 × 2 × 2 × 3 = 24
According to question:
24 = 1032 m – 408 × 5
24 = 1032 m – 2040
2064 = 1032 m
∴ m = ⇒ 2
Therefore m = 2
