Given numbers are 390, 272, 671, 577
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 272) = 53040
GCD(390, 272) = ( 390 x 272 ) / 53040
= 390 / 272
= 390
Step2:
LCM(2, 671) = 1342
GCD(2, 671) = ( 2 x 671 ) / 1342
= 2 / 671
= 2
Step3:
LCM(1, 577) = 577
GCD(1, 577) = ( 1 x 577 ) / 577
= 1 / 577
= 1
So, Greatest Common Divisor of 390, 272, 671, 577 is 1
