Given numbers are 170, 988, 129, 787

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

Apply this formula for all numbers.

Step1:

LCM(170, 988) = 83980

GCD(170, 988) = ( 170 x 988 ) / 83980

= 170 / 988

= 170

Step2:

LCM(2, 129) = 258

GCD(2, 129) = ( 2 x 129 ) / 258

= 2 / 129

= 2

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 170, 988, 129, 787 is 1
