Given numbers are 285, 621, 133, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 621) = 58995
GCD(285, 621) = ( 285 x 621 ) / 58995
= 285 / 621
= 285
Step2:
LCM(3, 133) = 399
GCD(3, 133) = ( 3 x 133 ) / 399
= 3 / 133
= 3
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 285, 621, 133, 809 is 1
