Given numbers are 680, 777, 711, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 777) = 528360
GCD(680, 777) = ( 680 x 777 ) / 528360
= 680 / 777
= 680
Step2:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 680, 777, 711, 455 is 1
