Given numbers are 203, 322, 130, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(203, 322) = 9338
GCD(203, 322) = ( 203 x 322 ) / 9338
= 203 / 322
= 203
Step2:
LCM(7, 130) = 910
GCD(7, 130) = ( 7 x 130 ) / 910
= 7 / 130
= 7
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 203, 322, 130, 790 is 1
