Given numbers are 727, 758, 205, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(727, 758) = 551066
GCD(727, 758) = ( 727 x 758 ) / 551066
= 727 / 758
= 727
Step2:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 727, 758, 205, 638 is 1
