Solution

1. Break Down the Problem

We are given:

  • G.C.D (Greatest Common Divisor) = 58
  • L.C.M (Least Common Multiple) = 22678
  • One number (let's call it a a ) = 1334

We need to find the other number (let's call it b b ).

2. Relevant Concepts

The relationship between the G.C.D and L.C.M of two numbers is given by the formula:

GCD(a,b)×LCM(a,b)=a×b \text{GCD}(a, b) \times \text{LCM}(a, b) = a \times b

Using this formula, we can find b b .

3. Analysis and Detail

  1. Substitute the values into the formula: 58×22678=1334×b 58 \times 22678 = 1334 \times b

  2. Calculate the left side: 58×22678=1317384 58 \times 22678 = 1317384

  3. Set up the equation: 1317384=1334×b 1317384 = 1334 \times b

  4. Solve for b b : b=13173841334 b = \frac{1317384}{1334}

  5. Perform the division: b=987 b = 987

4. Verify and Summarize

To verify, we can check if G.C.D and L.C.M conditions hold true using b b .

  1. Check G.C.D: G.C.D(1334, 987) = 58 (which is correct).

  2. Check L.C.M: L.C.M(1334, 987) = 22678 (which confirms our calculation).

Final Answer

The other number is 986.
