Given numbers are 665, 218, 918, 980

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 218 are 2 x 109

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 665, 218, 918, 980

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

Apply this formula for all numbers.

Step1:

LCM(665, 218) = 144970

GCD(665, 218) = ( 665 x 218 ) / 144970

= 665 / 218

= 665

Step2:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 665, 218, 918, 980 is 1
