Given numbers are 235, 640, 641, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(235, 640) = 30080
GCD(235, 640) = ( 235 x 640 ) / 30080
= 235 / 640
= 235
Step2:
LCM(5, 641) = 3205
GCD(5, 641) = ( 5 x 641 ) / 3205
= 5 / 641
= 5
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 235, 640, 641, 665 is 1
