Given numbers are 390, 820, 595, 547
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 820) = 31980
GCD(390, 820) = ( 390 x 820 ) / 31980
= 390 / 820
= 390
Step2:
LCM(10, 595) = 1190
GCD(10, 595) = ( 10 x 595 ) / 1190
= 10 / 595
= 10
Step3:
LCM(5, 547) = 2735
GCD(5, 547) = ( 5 x 547 ) / 2735
= 5 / 547
= 5
So, Greatest Common Divisor of 390, 820, 595, 547 is 1
