Given numbers are 644, 579, 29, 279

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

Apply this formula for all numbers.

Step1:

LCM(644, 579) = 372876

GCD(644, 579) = ( 644 x 579 ) / 372876

= 644 / 579

= 644

Step2:

LCM(1, 29) = 29

GCD(1, 29) = ( 1 x 29 ) / 29

= 1 / 29

= 1

Step3:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

So, Greatest Common Divisor of 644, 579, 29, 279 is 1
