Given numbers are 644, 627, 707, 211

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

Apply this formula for all numbers.

Step1:

LCM(644, 627) = 403788

GCD(644, 627) = ( 644 x 627 ) / 403788

= 644 / 627

= 644

Step2:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 644, 627, 707, 211 is 1
