Given numbers are 707, 699, 388, 642

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

Apply this formula for all numbers.

Step1:

LCM(707, 699) = 494193

GCD(707, 699) = ( 707 x 699 ) / 494193

= 707 / 699

= 707

Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 707, 699, 388, 642 is 1
