Given numbers are 644, 595, 709, 427

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

Apply this formula for all numbers.

Step1:

LCM(644, 595) = 54740

GCD(644, 595) = ( 644 x 595 ) / 54740

= 644 / 595

= 644

Step2:

LCM(7, 709) = 4963

GCD(7, 709) = ( 7 x 709 ) / 4963

= 7 / 709

= 7

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 644, 595, 709, 427 is 1
