Given numbers are 617, 669, 780, 711
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(617, 669) = 412773
GCD(617, 669) = ( 617 x 669 ) / 412773
= 617 / 669
= 617
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
So, Greatest Common Divisor of 617, 669, 780, 711 is 1
