Given numbers are 790, 495, 890, 987

The list of prime factors of all numbers are

Prime factors of 790 are 2 x 5 x 79

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 890 are 2 x 5 x 89

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 790, 495, 890, 987

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

Apply this formula for all numbers.

Step1:

LCM(790, 495) = 78210

GCD(790, 495) = ( 790 x 495 ) / 78210

= 790 / 495

= 790

Step2:

LCM(5, 890) = 890

GCD(5, 890) = ( 5 x 890 ) / 890

= 5 / 890

= 5

Step3:

LCM(5, 987) = 4935

GCD(5, 987) = ( 5 x 987 ) / 4935

= 5 / 987

= 5

So, Greatest Common Divisor of 790, 495, 890, 987 is 1
