Given numbers are 810, 259, 156, 676
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 259) = 209790
GCD(810, 259) = ( 810 x 259 ) / 209790
= 810 / 259
= 810
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
= 1 / 676
= 1
So, Greatest Common Divisor of 810, 259, 156, 676 is 1
