Given numbers are 420, 497, 204, 723
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 497) = 29820
GCD(420, 497) = ( 420 x 497 ) / 29820
= 420 / 497
= 420
Step2:
LCM(7, 204) = 1428
GCD(7, 204) = ( 7 x 204 ) / 1428
= 7 / 204
= 7
Step3:
LCM(1, 723) = 723
GCD(1, 723) = ( 1 x 723 ) / 723
= 1 / 723
= 1
So, Greatest Common Divisor of 420, 497, 204, 723 is 1
