Given numbers are 620, 969, 723, 942
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 969) = 600780
GCD(620, 969) = ( 620 x 969 ) / 600780
= 620 / 969
= 620
Step2:
LCM(1, 723) = 723
GCD(1, 723) = ( 1 x 723 ) / 723
= 1 / 723
= 1
Step3:
LCM(1, 942) = 942
GCD(1, 942) = ( 1 x 942 ) / 942
= 1 / 942
= 1
So, Greatest Common Divisor of 620, 969, 723, 942 is 1
