Given numbers are 233, 144, 646, 987

The list of prime factors of all numbers are

Prime factors of 233 are 233

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 646 are 2 x 17 x 19

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 233, 144, 646, 987

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

Apply this formula for all numbers.

Step1:

LCM(233, 144) = 33552

GCD(233, 144) = ( 233 x 144 ) / 33552

= 233 / 144

= 233

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 233, 144, 646, 987 is 1
