Given numbers are 669, 861, 262, 768

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

Apply this formula for all numbers.

Step1:

LCM(669, 861) = 192003

GCD(669, 861) = ( 669 x 861 ) / 192003

= 669 / 861

= 669

Step2:

LCM(3, 262) = 786

GCD(3, 262) = ( 3 x 262 ) / 786

= 3 / 262

= 3

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 669, 861, 262, 768 is 1
