Given numbers are 388, 497, 280, 506
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 497) = 192836
GCD(388, 497) = ( 388 x 497 ) / 192836
= 388 / 497
= 388
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
So, Greatest Common Divisor of 388, 497, 280, 506 is 1
