Given numbers are 646, 393, 86, 308

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

Apply this formula for all numbers.

Step1:

LCM(646, 393) = 253878

GCD(646, 393) = ( 646 x 393 ) / 253878

= 646 / 393

= 646

Step2:

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

= 1 / 86

= 1

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 646, 393, 86, 308 is 1
