Given numbers are 642, 697, 602, 620

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

Apply this formula for all numbers.

Step1:

LCM(642, 697) = 447474

GCD(642, 697) = ( 642 x 697 ) / 447474

= 642 / 697

= 642

Step2:

LCM(1, 602) = 602

GCD(1, 602) = ( 1 x 602 ) / 602

= 1 / 602

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 642, 697, 602, 620 is 1
