Given numbers are 621, 561, 215, 375

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(621, 561) = 116127

GCD(621, 561) = ( 621 x 561 ) / 116127

= 621 / 561

= 621

Step2:

LCM(3, 215) = 645

GCD(3, 215) = ( 3 x 215 ) / 645

= 3 / 215

= 3

Step3:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

So, Greatest Common Divisor of 621, 561, 215, 375 is 1
