LCM(5, 7) = 5×7 = 35

• 35 / 5 = 7.
• 35 / 7 = 5.

## How do you find the least common denominator with equivalent fractions?

Convert two fractions to equivalent fractions with their LCD as the common denominator

1. Find the LCD.
2. For each fraction, determine the number needed to multiply the denominator to get the LCD.
3. Use the Equivalent Fractions Property to multiply both the numerator and denominator by the number you found in Step 2.
