Given numbers are 644, 214, 281, 369

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

Apply this formula for all numbers.

Step1:

LCM(644, 214) = 68908

GCD(644, 214) = ( 644 x 214 ) / 68908

= 644 / 214

= 644

Step2:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

Step3:

LCM(1, 369) = 369

GCD(1, 369) = ( 1 x 369 ) / 369

= 1 / 369

= 1

So, Greatest Common Divisor of 644, 214, 281, 369 is 1
