Given numbers are 765, 140, 280, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 140) = 21420
GCD(765, 140) = ( 765 x 140 ) / 21420
= 765 / 140
= 765
Step2:
LCM(5, 280) = 280
GCD(5, 280) = ( 5 x 280 ) / 280
= 5 / 280
= 5
Step3:
LCM(5, 556) = 2780
GCD(5, 556) = ( 5 x 556 ) / 2780
= 5 / 556
= 5
So, Greatest Common Divisor of 765, 140, 280, 556 is 1
