GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 187) = 73678
GCD(394, 187) = ( 394 x 187 ) / 73678
= 394 / 187
= 394
Step2:
LCM(1, 379) = 379
GCD(1, 379) = ( 1 x 379 ) / 379
= 1 / 379
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 394, 187, 379, 644 is 1
