Given numbers are 890, 217, 832, 720

The list of prime factors of all numbers are

Prime factors of 890 are 2 x 5 x 89

Prime factors of 217 are 7 x 31

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 890, 217, 832, 720

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

Apply this formula for all numbers.

Step1:

LCM(890, 217) = 193130

GCD(890, 217) = ( 890 x 217 ) / 193130

= 890 / 217

= 890

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 890, 217, 832, 720 is 1
