Given numbers are 626, 407, 561, 671
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(626, 407) = 254782
GCD(626, 407) = ( 626 x 407 ) / 254782
= 626 / 407
= 626
Step2:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
Step3:
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
= 1 / 671
= 1
So, Greatest Common Divisor of 626, 407, 561, 671 is 1
