Given numbers are 628, 280, 429, 890

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

Apply this formula for all numbers.

Step1:

LCM(628, 280) = 43960

GCD(628, 280) = ( 628 x 280 ) / 43960

= 628 / 280

= 628

Step2:

LCM(4, 429) = 1716

GCD(4, 429) = ( 4 x 429 ) / 1716

= 4 / 429

= 4

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 628, 280, 429, 890 is 1
