Given numbers are 540, 819, 978, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(540, 819) = 49140
GCD(540, 819) = ( 540 x 819 ) / 49140
= 540 / 819
= 540
Step2:
LCM(9, 978) = 2934
GCD(9, 978) = ( 9 x 978 ) / 2934
= 9 / 978
= 9
Step3:
LCM(3, 770) = 2310
GCD(3, 770) = ( 3 x 770 ) / 2310
= 3 / 770
= 3
So, Greatest Common Divisor of 540, 819, 978, 770 is 1
