Given numbers are 429, 781, 629, 649

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

Apply this formula for all numbers.

Step1:

LCM(429, 781) = 30459

GCD(429, 781) = ( 429 x 781 ) / 30459

= 429 / 781

= 429

Step2:

LCM(11, 629) = 6919

GCD(11, 629) = ( 11 x 629 ) / 6919

= 11 / 629

= 11

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 429, 781, 629, 649 is 1
