GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 535) = 368615
GCD(689, 535) = ( 689 x 535 ) / 368615
= 689 / 535
= 689
Step2:
LCM(1, 196) = 196
GCD(1, 196) = ( 1 x 196 ) / 196
= 1 / 196
= 1
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 689, 535, 196, 399 is 1
