Given numbers are 644, 231, 101, 609

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

Apply this formula for all numbers.

Step1:

LCM(644, 231) = 21252

GCD(644, 231) = ( 644 x 231 ) / 21252

= 644 / 231

= 644

Step2:

LCM(7, 101) = 707

GCD(7, 101) = ( 7 x 101 ) / 707

= 7 / 101

= 7

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 644, 231, 101, 609 is 1
