Given numbers are 555, 996, 545, 978
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 996) = 184260
GCD(555, 996) = ( 555 x 996 ) / 184260
= 555 / 996
= 555
Step2:
LCM(3, 545) = 1635
GCD(3, 545) = ( 3 x 545 ) / 1635
= 3 / 545
= 3
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 555, 996, 545, 978 is 1
