Given numbers are 870, 278, 164, 259
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 278) = 120930
GCD(870, 278) = ( 870 x 278 ) / 120930
= 870 / 278
= 870
Step2:
LCM(2, 164) = 164
GCD(2, 164) = ( 2 x 164 ) / 164
= 2 / 164
= 2
Step3:
LCM(2, 259) = 518
GCD(2, 259) = ( 2 x 259 ) / 518
= 2 / 259
= 2
So, Greatest Common Divisor of 870, 278, 164, 259 is 1
