GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 672) = 265440
GCD(395, 672) = ( 395 x 672 ) / 265440
= 395 / 672
= 395
Step2:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 395, 672, 388, 820 is 1
