Given numbers are 646, 343, 682, 652

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

Apply this formula for all numbers.

Step1:

LCM(646, 343) = 221578

GCD(646, 343) = ( 646 x 343 ) / 221578

= 646 / 343

= 646

Step2:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 646, 343, 682, 652 is 1
