Given numbers are 644, 260, 938, 452

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

Apply this formula for all numbers.

Step1:

LCM(644, 260) = 41860

GCD(644, 260) = ( 644 x 260 ) / 41860

= 644 / 260

= 644

Step2:

LCM(4, 938) = 1876

GCD(4, 938) = ( 4 x 938 ) / 1876

= 4 / 938

= 4

Step3:

LCM(2, 452) = 452

GCD(2, 452) = ( 2 x 452 ) / 452

= 2 / 452

= 2

So, Greatest Common Divisor of 644, 260, 938, 452 is 2
