Given numbers are 771, 698, 30, 393

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

Apply this formula for all numbers.

Step1:

LCM(771, 698) = 538158

GCD(771, 698) = ( 771 x 698 ) / 538158

= 771 / 698

= 771

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 771, 698, 30, 393 is 1
