GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 789) = 109671
GCD(417, 789) = ( 417 x 789 ) / 109671
= 417 / 789
= 417
Step2:
LCM(3, 538) = 1614
GCD(3, 538) = ( 3 x 538 ) / 1614
= 3 / 538
= 3
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 417, 789, 538, 280 is 1
