Given numbers are 657, 312, 245, 579

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

Apply this formula for all numbers.

Step1:

LCM(657, 312) = 68328

GCD(657, 312) = ( 657 x 312 ) / 68328

= 657 / 312

= 657

Step2:

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

= 3 / 245

= 3

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 657, 312, 245, 579 is 1
