Given numbers are 502, 143, 551, 639

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

Apply this formula for all numbers.

Step1:

LCM(502, 143) = 71786

GCD(502, 143) = ( 502 x 143 ) / 71786

= 502 / 143

= 502

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 502, 143, 551, 639 is 1
