Given numbers are 123, 751, 978, 864

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 751 are 751

Prime factors of 978 are 2 x 3 x 163

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 123, 751, 978, 864

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

Apply this formula for all numbers.

Step1:

LCM(123, 751) = 92373

GCD(123, 751) = ( 123 x 751 ) / 92373

= 123 / 751

= 123

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 123, 751, 978, 864 is 1
