Given numbers are 420, 258, 752, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 258) = 18060
GCD(420, 258) = ( 420 x 258 ) / 18060
= 420 / 258
= 420
Step2:
LCM(6, 752) = 2256
GCD(6, 752) = ( 6 x 752 ) / 2256
= 6 / 752
= 6
Step3:
LCM(2, 389) = 778
GCD(2, 389) = ( 2 x 389 ) / 778
= 2 / 389
= 2
So, Greatest Common Divisor of 420, 258, 752, 389 is 1
