Given numbers are 226, 770, 399, 643

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

Apply this formula for all numbers.

Step1:

LCM(226, 770) = 87010

GCD(226, 770) = ( 226 x 770 ) / 87010

= 226 / 770

= 226

Step2:

LCM(2, 399) = 798

GCD(2, 399) = ( 2 x 399 ) / 798

= 2 / 399

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 226, 770, 399, 643 is 1
