Given numbers are 646, 860, 558, 179

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

Apply this formula for all numbers.

Step1:

LCM(646, 860) = 277780

GCD(646, 860) = ( 646 x 860 ) / 277780

= 646 / 860

= 646

Step2:

LCM(2, 558) = 558

GCD(2, 558) = ( 2 x 558 ) / 558

= 2 / 558

= 2

Step3:

LCM(2, 179) = 358

GCD(2, 179) = ( 2 x 179 ) / 358

= 2 / 179

= 2

So, Greatest Common Divisor of 646, 860, 558, 179 is 1
