Given numbers are 707, 686, 193, 128

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

Apply this formula for all numbers.

Step1:

LCM(707, 686) = 69286

GCD(707, 686) = ( 707 x 686 ) / 69286

= 707 / 686

= 707

Step2:

LCM(7, 193) = 1351

GCD(7, 193) = ( 7 x 193 ) / 1351

= 7 / 193

= 7

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 707, 686, 193, 128 is 1
