Given numbers are 749, 890, 280

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

Apply this formula for all numbers.

Step1:

LCM(749, 890) = 666610

GCD(749, 890) = ( 749 x 890 ) / 666610

= 749 / 890

= 749

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 749, 890, 280 is 1
