Given numbers are 102, 680, 859, 689

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

Apply this formula for all numbers.

Step1:

LCM(102, 680) = 2040

GCD(102, 680) = ( 102 x 680 ) / 2040

= 102 / 680

= 102

Step2:

LCM(34, 859) = 29206

GCD(34, 859) = ( 34 x 859 ) / 29206

= 34 / 859

= 34

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 102, 680, 859, 689 is 1
