Given numbers are 621, 675, 411, 491

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

Apply this formula for all numbers.

Step1:

LCM(621, 675) = 15525

GCD(621, 675) = ( 621 x 675 ) / 15525

= 621 / 675

= 621

Step2:

LCM(27, 411) = 3699

GCD(27, 411) = ( 27 x 411 ) / 3699

= 27 / 411

= 27

Step3:

LCM(3, 491) = 1473

GCD(3, 491) = ( 3 x 491 ) / 1473

= 3 / 491

= 3

So, Greatest Common Divisor of 621, 675, 411, 491 is 1
