GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 329) = 256949
GCD(781, 329) = ( 781 x 329 ) / 256949
= 781 / 329
= 781
Step2:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 781, 329, 202, 399 is 1
