Given numbers are 642, 625, 990, 226

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

Apply this formula for all numbers.

Step1:

LCM(642, 625) = 401250

GCD(642, 625) = ( 642 x 625 ) / 401250

= 642 / 625

= 642

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 226) = 226

GCD(1, 226) = ( 1 x 226 ) / 226

= 1 / 226

= 1

So, Greatest Common Divisor of 642, 625, 990, 226 is 1
