Given numbers are 646, 834, 545, 488

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

Apply this formula for all numbers.

Step1:

LCM(646, 834) = 269382

GCD(646, 834) = ( 646 x 834 ) / 269382

= 646 / 834

= 646

Step2:

LCM(2, 545) = 1090

GCD(2, 545) = ( 2 x 545 ) / 1090

= 2 / 545

= 2

Step3:

LCM(1, 488) = 488

GCD(1, 488) = ( 1 x 488 ) / 488

= 1 / 488

= 1

So, Greatest Common Divisor of 646, 834, 545, 488 is 1
