GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(286, 162) = 23166
GCD(286, 162) = ( 286 x 162 ) / 23166
= 286 / 162
= 286
Step2:
LCM(2, 456) = 456
GCD(2, 456) = ( 2 x 456 ) / 456
= 2 / 456
= 2
Step3:
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
= 2 / 278
= 2
So, Greatest Common Divisor of 286, 162, 456, 278 is 2
