GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 266) = 56924
GCD(428, 266) = ( 428 x 266 ) / 56924
= 428 / 266
= 428
Step2:
LCM(2, 133) = 266
GCD(2, 133) = ( 2 x 133 ) / 266
= 2 / 133
= 2
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 428, 266, 133, 809 is 1
