Given numbers are 644, 246, 986, 565

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

Apply this formula for all numbers.

Step1:

LCM(644, 246) = 79212

GCD(644, 246) = ( 644 x 246 ) / 79212

= 644 / 246

= 644

Step2:

LCM(2, 986) = 986

GCD(2, 986) = ( 2 x 986 ) / 986

= 2 / 986

= 2

Step3:

LCM(2, 565) = 1130

GCD(2, 565) = ( 2 x 565 ) / 1130

= 2 / 565

= 2

So, Greatest Common Divisor of 644, 246, 986, 565 is 1
