GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 176) = 113520
GCD(645, 176) = ( 645 x 176 ) / 113520
= 645 / 176
= 645
Step2:
LCM(1, 366) = 366
GCD(1, 366) = ( 1 x 366 ) / 366
= 1 / 366
= 1
Step3:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
So, Greatest Common Divisor of 645, 176, 366, 395 is 1
