Given numbers are 212, 745, 777, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 745) = 157940
GCD(212, 745) = ( 212 x 745 ) / 157940
= 212 / 745
= 212
Step2:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 212, 745, 777, 287 is 1
