Given numbers are 425, 305, 737, 647

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(425, 305) = 25925

GCD(425, 305) = ( 425 x 305 ) / 25925

= 425 / 305

= 425

Step2:

LCM(5, 737) = 3685

GCD(5, 737) = ( 5 x 737 ) / 3685

= 5 / 737

= 5

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 425, 305, 737, 647 is 1
