Given numbers are 978, 621, 252, 160

The list of prime factors of all numbers are

Prime factors of 978 are 2 x 3 x 163

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

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

Given numbers are 978, 621, 252, 160

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

Apply this formula for all numbers.

Step1:

LCM(978, 621) = 202446

GCD(978, 621) = ( 978 x 621 ) / 202446

= 978 / 621

= 978

Step2:

LCM(3, 252) = 252

GCD(3, 252) = ( 3 x 252 ) / 252

= 3 / 252

= 3

Step3:

LCM(3, 160) = 480

GCD(3, 160) = ( 3 x 160 ) / 480

= 3 / 160

= 3

So, Greatest Common Divisor of 978, 621, 252, 160 is 1
