Given numbers are 866, 784, 470, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(866, 784) = 339472
GCD(866, 784) = ( 866 x 784 ) / 339472
= 866 / 784
= 866
Step2:
LCM(2, 470) = 470
GCD(2, 470) = ( 2 x 470 ) / 470
= 2 / 470
= 2
Step3:
LCM(2, 355) = 710
GCD(2, 355) = ( 2 x 355 ) / 710
= 2 / 355
= 2
So, Greatest Common Divisor of 866, 784, 470, 355 is 1
