Given numbers are 646, 475, 124, 349

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

Apply this formula for all numbers.

Step1:

LCM(646, 475) = 16150

GCD(646, 475) = ( 646 x 475 ) / 16150

= 646 / 475

= 646

Step2:

LCM(19, 124) = 2356

GCD(19, 124) = ( 19 x 124 ) / 2356

= 19 / 124

= 19

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 646, 475, 124, 349 is 1
