Given numbers are 298, 430, 238, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(298, 430) = 64070
GCD(298, 430) = ( 298 x 430 ) / 64070
= 298 / 430
= 298
Step2:
LCM(2, 238) = 238
GCD(2, 238) = ( 2 x 238 ) / 238
= 2 / 238
= 2
Step3:
LCM(2, 445) = 890
GCD(2, 445) = ( 2 x 445 ) / 890
= 2 / 445
= 2
So, Greatest Common Divisor of 298, 430, 238, 445 is 1
