Given numbers are 120, 426, 903, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 426) = 8520
GCD(120, 426) = ( 120 x 426 ) / 8520
= 120 / 426
= 120
Step2:
LCM(6, 903) = 1806
GCD(6, 903) = ( 6 x 903 ) / 1806
= 6 / 903
= 6
Step3:
LCM(3, 280) = 840
GCD(3, 280) = ( 3 x 280 ) / 840
= 3 / 280
= 3
So, Greatest Common Divisor of 120, 426, 903, 280 is 1
