Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 5.5.

The greatest number that can divide 286, 1001, and 2420 is X = H.C.F. of 286, 1001, and 2420

Prime factorization of

⇒ 286 = 2 × 13 × 11

⇒ 1001 = 7 × 13 × 11

⇒ 2420 = 2 × 2 × 5 × 11 × 11

H.C.F of 286, 1001, and 2420 = 11

Hence,

Required number = X/2 = 11/2 = 5.5
