Given numbers are 890, 416, 643, 815

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

Apply this formula for all numbers.

Step1:

LCM(890, 416) = 185120

GCD(890, 416) = ( 890 x 416 ) / 185120

= 890 / 416

= 890

Step2:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 890, 416, 643, 815 is 1
