Given numbers are 529, 368, 138, 646

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

Apply this formula for all numbers.

Step1:

LCM(529, 368) = 8464

GCD(529, 368) = ( 529 x 368 ) / 8464

= 529 / 368

= 529

Step2:

LCM(23, 138) = 138

GCD(23, 138) = ( 23 x 138 ) / 138

= 23 / 138

= 23

Step3:

LCM(23, 646) = 14858

GCD(23, 646) = ( 23 x 646 ) / 14858

= 23 / 646

= 23

So, Greatest Common Divisor of 529, 368, 138, 646 is 1
