Given numbers are 408, 921, 778, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 921) = 125256
GCD(408, 921) = ( 408 x 921 ) / 125256
= 408 / 921
= 408
Step2:
LCM(3, 778) = 2334
GCD(3, 778) = ( 3 x 778 ) / 2334
= 3 / 778
= 3
Step3:
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
= 1 / 697
= 1
So, Greatest Common Divisor of 408, 921, 778, 697 is 1
