Given numbers are 644, 651, 73, 329

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

Apply this formula for all numbers.

Step1:

LCM(644, 651) = 59892

GCD(644, 651) = ( 644 x 651 ) / 59892

= 644 / 651

= 644

Step2:

LCM(7, 73) = 511

GCD(7, 73) = ( 7 x 73 ) / 511

= 7 / 73

= 7

Step3:

LCM(1, 329) = 329

GCD(1, 329) = ( 1 x 329 ) / 329

= 1 / 329

= 1

So, Greatest Common Divisor of 644, 651, 73, 329 is 1
