Given numbers are 781, 344, 356, 415

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

Apply this formula for all numbers.

Step1:

LCM(781, 344) = 268664

GCD(781, 344) = ( 781 x 344 ) / 268664

= 781 / 344

= 781

Step2:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 781, 344, 356, 415 is 1
