Given numbers are 620, 688, 68, 652

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

Apply this formula for all numbers.

Step1:

LCM(620, 688) = 106640

GCD(620, 688) = ( 620 x 688 ) / 106640

= 620 / 688

= 620

Step2:

LCM(4, 68) = 68

GCD(4, 68) = ( 4 x 68 ) / 68

= 4 / 68

= 4

Step3:

LCM(4, 652) = 652

GCD(4, 652) = ( 4 x 652 ) / 652

= 4 / 652

= 4

So, Greatest Common Divisor of 620, 688, 68, 652 is 4
