Given numbers are 639, 492, 54, 856

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

Apply this formula for all numbers.

Step1:

LCM(639, 492) = 104796

GCD(639, 492) = ( 639 x 492 ) / 104796

= 639 / 492

= 639

Step2:

LCM(3, 54) = 54

GCD(3, 54) = ( 3 x 54 ) / 54

= 3 / 54

= 3

Step3:

LCM(3, 856) = 2568

GCD(3, 856) = ( 3 x 856 ) / 2568

= 3 / 856

= 3

So, Greatest Common Divisor of 639, 492, 54, 856 is 1
