Given numbers are 153, 980, 244, 981

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

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

Prime factors of 244 are 2 x 2 x 61

Prime factors of 981 are 3 x 3 x 109

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

Given numbers are 153, 980, 244, 981

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

Apply this formula for all numbers.

Step1:

LCM(153, 980) = 149940

GCD(153, 980) = ( 153 x 980 ) / 149940

= 153 / 980

= 153

Step2:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 153, 980, 244, 981 is 1
