Given numbers are 680, 215, 109, 869

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

Apply this formula for all numbers.

Step1:

LCM(680, 215) = 29240

GCD(680, 215) = ( 680 x 215 ) / 29240

= 680 / 215

= 680

Step2:

LCM(5, 109) = 545

GCD(5, 109) = ( 5 x 109 ) / 545

= 5 / 109

= 5

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 680, 215, 109, 869 is 1
