Given numbers are 676, 726, 849, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 726) = 245388
GCD(676, 726) = ( 676 x 726 ) / 245388
= 676 / 726
= 676
Step2:
LCM(2, 849) = 1698
GCD(2, 849) = ( 2 x 849 ) / 1698
= 2 / 849
= 2
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 676, 726, 849, 390 is 1
