Given numbers are 420, 884, 117, 409

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

Apply this formula for all numbers.

Step1:

LCM(420, 884) = 92820

GCD(420, 884) = ( 420 x 884 ) / 92820

= 420 / 884

= 420

Step2:

LCM(4, 117) = 468

GCD(4, 117) = ( 4 x 117 ) / 468

= 4 / 117

= 4

Step3:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

So, Greatest Common Divisor of 420, 884, 117, 409 is 1
