Given numbers are 646, 196, 554, 160

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

Apply this formula for all numbers.

Step1:

LCM(646, 196) = 63308

GCD(646, 196) = ( 646 x 196 ) / 63308

= 646 / 196

= 646

Step2:

LCM(2, 554) = 554

GCD(2, 554) = ( 2 x 554 ) / 554

= 2 / 554

= 2

Step3:

LCM(2, 160) = 160

GCD(2, 160) = ( 2 x 160 ) / 160

= 2 / 160

= 2

So, Greatest Common Divisor of 646, 196, 554, 160 is 2
