Given numbers are 280, 210, 517, 874
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 210) = 840
GCD(280, 210) = ( 280 x 210 ) / 840
= 280 / 210
= 280
Step2:
LCM(70, 517) = 36190
GCD(70, 517) = ( 70 x 517 ) / 36190
= 70 / 517
= 70
Step3:
LCM(1, 874) = 874
GCD(1, 874) = ( 1 x 874 ) / 874
= 1 / 874
= 1
So, Greatest Common Divisor of 280, 210, 517, 874 is 1
