Given numbers are 790, 575, 657, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 575) = 90850
GCD(790, 575) = ( 790 x 575 ) / 90850
= 790 / 575
= 790
Step2:
LCM(5, 657) = 3285
GCD(5, 657) = ( 5 x 657 ) / 3285
= 5 / 657
= 5
Step3:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
So, Greatest Common Divisor of 790, 575, 657, 395 is 1
