Given numbers are 646, 338, 611, 895

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

Apply this formula for all numbers.

Step1:

LCM(646, 338) = 109174

GCD(646, 338) = ( 646 x 338 ) / 109174

= 646 / 338

= 646

Step2:

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

= 2 / 611

= 2

Step3:

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

= 1 / 895

= 1

So, Greatest Common Divisor of 646, 338, 611, 895 is 1
