Given numbers are 621, 145, 557, 401

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

Apply this formula for all numbers.

Step1:

LCM(621, 145) = 90045

GCD(621, 145) = ( 621 x 145 ) / 90045

= 621 / 145

= 621

Step2:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 621, 145, 557, 401 is 1
