Given numbers are 473, 781, 641, 665

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

Apply this formula for all numbers.

Step1:

LCM(473, 781) = 33583

GCD(473, 781) = ( 473 x 781 ) / 33583

= 473 / 781

= 473

Step2:

LCM(11, 641) = 7051

GCD(11, 641) = ( 11 x 641 ) / 7051

= 11 / 641

= 11

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 473, 781, 641, 665 is 1
