Given numbers are 978, 145, 160, 248

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 145 are 5 x 29

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 978, 145, 160, 248

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

Apply this formula for all numbers.

Step1:

LCM(978, 145) = 141810

GCD(978, 145) = ( 978 x 145 ) / 141810

= 978 / 145

= 978

Step2:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 978, 145, 160, 248 is 1
