GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 395) = 259515
GCD(657, 395) = ( 657 x 395 ) / 259515
= 657 / 395
= 657
Step2:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 657, 395, 475, 580 is 1
