Given numbers are 126, 123, 809, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 123) = 5166
GCD(126, 123) = ( 126 x 123 ) / 5166
= 126 / 123
= 126
Step2:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 126, 123, 809, 531 is 1
