Given numbers are 642, 436, 890, 229

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

Apply this formula for all numbers.

Step1:

LCM(642, 436) = 139956

GCD(642, 436) = ( 642 x 436 ) / 139956

= 642 / 436

= 642

Step2:

LCM(2, 890) = 890

GCD(2, 890) = ( 2 x 890 ) / 890

= 2 / 890

= 2

Step3:

LCM(2, 229) = 458

GCD(2, 229) = ( 2 x 229 ) / 458

= 2 / 229

= 2

So, Greatest Common Divisor of 642, 436, 890, 229 is 1
