Given numbers are 392, 247, 391, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 247) = 96824
GCD(392, 247) = ( 392 x 247 ) / 96824
= 392 / 247
= 392
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
So, Greatest Common Divisor of 392, 247, 391, 671 is 1
