Given numbers are 978, 860, 919, 958
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 860) = 420540
GCD(978, 860) = ( 978 x 860 ) / 420540
= 978 / 860
= 978
Step2:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
Step3:
LCM(1, 958) = 958
GCD(1, 958) = ( 1 x 958 ) / 958
= 1 / 958
= 1
So, Greatest Common Divisor of 978, 860, 919, 958 is 1
