Given numbers are 686, 455, 652, 164

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

Apply this formula for all numbers.

Step1:

LCM(686, 455) = 44590

GCD(686, 455) = ( 686 x 455 ) / 44590

= 686 / 455

= 686

Step2:

LCM(7, 652) = 4564

GCD(7, 652) = ( 7 x 652 ) / 4564

= 7 / 652

= 7

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 686, 455, 652, 164 is 1
