Given numbers are 658, 788, 430, 869

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

Apply this formula for all numbers.

Step1:

LCM(658, 788) = 259252

GCD(658, 788) = ( 658 x 788 ) / 259252

= 658 / 788

= 658

Step2:

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

= 2 / 430

= 2

Step3:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

So, Greatest Common Divisor of 658, 788, 430, 869 is 1
