Given numbers are 668, 768, 129, 956

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

Apply this formula for all numbers.

Step1:

LCM(668, 768) = 128256

GCD(668, 768) = ( 668 x 768 ) / 128256

= 668 / 768

= 668

Step2:

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

= 4 / 129

= 4

Step3:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

So, Greatest Common Divisor of 668, 768, 129, 956 is 1
