Given numbers are 875, 668, 280, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(875, 668) = 584500
GCD(875, 668) = ( 875 x 668 ) / 584500
= 875 / 668
= 875
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
So, Greatest Common Divisor of 875, 668, 280, 403 is 1
