Given numbers are 637, 279, 395, 209
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 279) = 177723
GCD(637, 279) = ( 637 x 279 ) / 177723
= 637 / 279
= 637
Step2:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 637, 279, 395, 209 is 1
