Given numbers are 781, 697, 615, 368

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

Apply this formula for all numbers.

Step1:

LCM(781, 697) = 544357

GCD(781, 697) = ( 781 x 697 ) / 544357

= 781 / 697

= 781

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

So, Greatest Common Divisor of 781, 697, 615, 368 is 1
