Given numbers are 280, 426, 398, 235
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 426) = 59640
GCD(280, 426) = ( 280 x 426 ) / 59640
= 280 / 426
= 280
Step2:
LCM(2, 398) = 398
GCD(2, 398) = ( 2 x 398 ) / 398
= 2 / 398
= 2
Step3:
LCM(2, 235) = 470
GCD(2, 235) = ( 2 x 235 ) / 470
= 2 / 235
= 2
So, Greatest Common Divisor of 280, 426, 398, 235 is 1
