Given numbers are 680, 717, 792, 256
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 717) = 487560
GCD(680, 717) = ( 680 x 717 ) / 487560
= 680 / 717
= 680
Step2:
LCM(1, 792) = 792
GCD(1, 792) = ( 1 x 792 ) / 792
= 1 / 792
= 1
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 680, 717, 792, 256 is 1
