Given numbers are 280, 994, 308, 623
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 994) = 19880
GCD(280, 994) = ( 280 x 994 ) / 19880
= 280 / 994
= 280
Step2:
LCM(14, 308) = 308
GCD(14, 308) = ( 14 x 308 ) / 308
= 14 / 308
= 14
Step3:
LCM(14, 623) = 1246
GCD(14, 623) = ( 14 x 623 ) / 1246
= 14 / 623
= 14
So, Greatest Common Divisor of 280, 994, 308, 623 is 7
