Given numbers are 644, 634, 718, 193

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

Apply this formula for all numbers.

Step1:

LCM(644, 634) = 204148

GCD(644, 634) = ( 644 x 634 ) / 204148

= 644 / 634

= 644

Step2:

LCM(2, 718) = 718

GCD(2, 718) = ( 2 x 718 ) / 718

= 2 / 718

= 2

Step3:

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

= 2 / 193

= 2

So, Greatest Common Divisor of 644, 634, 718, 193 is 1
