Given numbers are 409, 872, 832, 661

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

Apply this formula for all numbers.

Step1:

LCM(409, 872) = 356648

GCD(409, 872) = ( 409 x 872 ) / 356648

= 409 / 872

= 409

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 661) = 661

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

= 1 / 661

= 1

So, Greatest Common Divisor of 409, 872, 832, 661 is 1
