Given numbers are 395, 655, 571, 764
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 655) = 51745
GCD(395, 655) = ( 395 x 655 ) / 51745
= 395 / 655
= 395
Step2:
LCM(5, 571) = 2855
GCD(5, 571) = ( 5 x 571 ) / 2855
= 5 / 571
= 5
Step3:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
So, Greatest Common Divisor of 395, 655, 571, 764 is 1
