Given numbers are 578, 644, 816, 629

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

Apply this formula for all numbers.

Step1:

LCM(578, 644) = 186116

GCD(578, 644) = ( 578 x 644 ) / 186116

= 578 / 644

= 578

Step2:

LCM(2, 816) = 816

GCD(2, 816) = ( 2 x 816 ) / 816

= 2 / 816

= 2

Step3:

LCM(2, 629) = 1258

GCD(2, 629) = ( 2 x 629 ) / 1258

= 2 / 629

= 2

So, Greatest Common Divisor of 578, 644, 816, 629 is 1
