Numbers: 85 and 255
Least Common Multiple (LCM) = 85R + 255
Formula Used:
LCM = (Product of numbers) / (Greatest Common Divisor (GCD))
Calculation:
⇒ LCM (85, 255) = 255
⇒ LCM = 85R + 255
Substitute LCM = 255 into the equation:
⇒ 255 = 85R + 255
⇒ 85R = 255 - 255
⇒ 85R = 0
⇒ R = 0
The value of R is 0.
