Given numbers are 720, 578, 556, 977
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 578) = 208080
GCD(720, 578) = ( 720 x 578 ) / 208080
= 720 / 578
= 720
Step2:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
Step3:
LCM(2, 977) = 1954
GCD(2, 977) = ( 2 x 977 ) / 1954
= 2 / 977
= 2
So, Greatest Common Divisor of 720, 578, 556, 977 is 1
