Given numbers are 207, 451, 644, 835

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

Apply this formula for all numbers.

Step1:

LCM(207, 451) = 93357

GCD(207, 451) = ( 207 x 451 ) / 93357

= 207 / 451

= 207

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 207, 451, 644, 835 is 1
