Given numbers are 787, 691, 54, 681

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

Apply this formula for all numbers.

Step1:

LCM(787, 691) = 543817

GCD(787, 691) = ( 787 x 691 ) / 543817

= 787 / 691

= 787

Step2:

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

= 1 / 54

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 787, 691, 54, 681 is 1
