Given numbers are 769, 324, 79, 661

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

Apply this formula for all numbers.

Step1:

LCM(769, 324) = 249156

GCD(769, 324) = ( 769 x 324 ) / 249156

= 769 / 324

= 769

Step2:

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

= 1 / 79

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 769, 324, 79, 661 is 1
