Given numbers are 688, 322, 218, 879
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 322) = 110768
GCD(688, 322) = ( 688 x 322 ) / 110768
= 688 / 322
= 688
Step2:
LCM(2, 218) = 218
GCD(2, 218) = ( 2 x 218 ) / 218
= 2 / 218
= 2
Step3:
LCM(2, 879) = 1758
GCD(2, 879) = ( 2 x 879 ) / 1758
= 2 / 879
= 2
So, Greatest Common Divisor of 688, 322, 218, 879 is 1
