Given numbers are 680, 652, 362, 638

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

Apply this formula for all numbers.

Step1:

LCM(680, 652) = 110840

GCD(680, 652) = ( 680 x 652 ) / 110840

= 680 / 652

= 680

Step2:

LCM(4, 362) = 724

GCD(4, 362) = ( 4 x 362 ) / 724

= 4 / 362

= 4

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 680, 652, 362, 638 is 2
