Given numbers are 308, 280, 829, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 280) = 3080
GCD(308, 280) = ( 308 x 280 ) / 3080
= 308 / 280
= 308
Step2:
LCM(28, 829) = 23212
GCD(28, 829) = ( 28 x 829 ) / 23212
= 28 / 829
= 28
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 308, 280, 829, 249 is 1
