Given numbers are 454, 388, 641, 661

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

Apply this formula for all numbers.

Step1:

LCM(454, 388) = 88076

GCD(454, 388) = ( 454 x 388 ) / 88076

= 454 / 388

= 454

Step2:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 454, 388, 641, 661 is 1
