Given numbers are 781, 215, 409, 632

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

Apply this formula for all numbers.

Step1:

LCM(781, 215) = 167915

GCD(781, 215) = ( 781 x 215 ) / 167915

= 781 / 215

= 781

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

So, Greatest Common Divisor of 781, 215, 409, 632 is 1
