Given numbers are 644, 958, 873, 218

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

Apply this formula for all numbers.

Step1:

LCM(644, 958) = 308476

GCD(644, 958) = ( 644 x 958 ) / 308476

= 644 / 958

= 644

Step2:

LCM(2, 873) = 1746

GCD(2, 873) = ( 2 x 873 ) / 1746

= 2 / 873

= 2

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 644, 958, 873, 218 is 1
