Given numbers are 208, 280, 395, 804
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 280) = 7280
GCD(208, 280) = ( 208 x 280 ) / 7280
= 208 / 280
= 208
Step2:
LCM(8, 395) = 3160
GCD(8, 395) = ( 8 x 395 ) / 3160
= 8 / 395
= 8
Step3:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
So, Greatest Common Divisor of 208, 280, 395, 804 is 1
