Given numbers are 628, 157, 209, 169

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

Apply this formula for all numbers.

Step1:

LCM(628, 157) = 628

GCD(628, 157) = ( 628 x 157 ) / 628

= 628 / 157

= 628

Step2:

LCM(157, 209) = 32813

GCD(157, 209) = ( 157 x 209 ) / 32813

= 157 / 209

= 157

Step3:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

So, Greatest Common Divisor of 628, 157, 209, 169 is 1
