Given numbers are 189, 416, 223, 840

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

Apply this formula for all numbers.

Step1:

LCM(189, 416) = 78624

GCD(189, 416) = ( 189 x 416 ) / 78624

= 189 / 416

= 189

Step2:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 189, 416, 223, 840 is 1
