GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 202) = 78578
GCD(389, 202) = ( 389 x 202 ) / 78578
= 389 / 202
= 389
Step2:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 389, 202, 486, 603 is 1
