Given numbers are 866, 778, 455, 434
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(866, 778) = 336874
GCD(866, 778) = ( 866 x 778 ) / 336874
= 866 / 778
= 866
Step2:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
Step3:
LCM(1, 434) = 434
GCD(1, 434) = ( 1 x 434 ) / 434
= 1 / 434
= 1
So, Greatest Common Divisor of 866, 778, 455, 434 is 1
