Given numbers are 659, 909, 207, 478

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

Apply this formula for all numbers.

Step1:

LCM(659, 909) = 599031

GCD(659, 909) = ( 659 x 909 ) / 599031

= 659 / 909

= 659

Step2:

LCM(1, 207) = 207

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

= 1 / 207

= 1

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 659, 909, 207, 478 is 1
