Given numbers are 443, 121, 291, 661

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

Apply this formula for all numbers.

Step1:

LCM(443, 121) = 53603

GCD(443, 121) = ( 443 x 121 ) / 53603

= 443 / 121

= 443

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

Step3:

LCM(1, 661) = 661

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

= 1 / 661

= 1

So, Greatest Common Divisor of 443, 121, 291, 661 is 1
