Given numbers are 695, 494, 668, 209
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 494) = 343330
GCD(695, 494) = ( 695 x 494 ) / 343330
= 695 / 494
= 695
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 695, 494, 668, 209 is 1
