Given numbers are 129, 206, 202, 770

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

Apply this formula for all numbers.

Step1:

LCM(129, 206) = 26574

GCD(129, 206) = ( 129 x 206 ) / 26574

= 129 / 206

= 129

Step2:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 129, 206, 202, 770 is 1
