Given numbers are 407, 189, 207, 707

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

Apply this formula for all numbers.

Step1:

LCM(407, 189) = 76923

GCD(407, 189) = ( 407 x 189 ) / 76923

= 407 / 189

= 407

Step2:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

Step3:

LCM(1, 707) = 707

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

= 1 / 707

= 1

So, Greatest Common Divisor of 407, 189, 207, 707 is 1
