Given numbers are 285, 639, 143, 942

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

Apply this formula for all numbers.

Step1:

LCM(285, 639) = 60705

GCD(285, 639) = ( 285 x 639 ) / 60705

= 285 / 639

= 285

Step2:

LCM(3, 143) = 429

GCD(3, 143) = ( 3 x 143 ) / 429

= 3 / 143

= 3

Step3:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

So, Greatest Common Divisor of 285, 639, 143, 942 is 1
