Given numbers are 872, 390, 403, 186
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(872, 390) = 170040
GCD(872, 390) = ( 872 x 390 ) / 170040
= 872 / 390
= 872
Step2:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
Step3:
LCM(1, 186) = 186
GCD(1, 186) = ( 1 x 186 ) / 186
= 1 / 186
= 1
So, Greatest Common Divisor of 872, 390, 403, 186 is 1
