Given numbers are 485, 500, 388, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 500) = 48500
GCD(485, 500) = ( 485 x 500 ) / 48500
= 485 / 500
= 485
Step2:
LCM(5, 388) = 1940
GCD(5, 388) = ( 5 x 388 ) / 1940
= 5 / 388
= 5
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 485, 500, 388, 657 is 1
