GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 945) = 128520
GCD(408, 945) = ( 408 x 945 ) / 128520
= 408 / 945
= 408
Step2:
LCM(3, 879) = 879
GCD(3, 879) = ( 3 x 879 ) / 879
= 3 / 879
= 3
Step3:
LCM(3, 207) = 207
GCD(3, 207) = ( 3 x 207 ) / 207
= 3 / 207
= 3
So, Greatest Common Divisor of 408, 945, 879, 207 is 3
