Given numbers are 243, 778, 62, 691

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

Apply this formula for all numbers.

Step1:

LCM(243, 778) = 189054

GCD(243, 778) = ( 243 x 778 ) / 189054

= 243 / 778

= 243

Step2:

LCM(1, 62) = 62

GCD(1, 62) = ( 1 x 62 ) / 62

= 1 / 62

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 243, 778, 62, 691 is 1
