Given numbers are 261, 661, 479, 407

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

Apply this formula for all numbers.

Step1:

LCM(261, 661) = 172521

GCD(261, 661) = ( 261 x 661 ) / 172521

= 261 / 661

= 261

Step2:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 261, 661, 479, 407 is 1
