Given numbers are 660, 805, 481, 978

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 805 are 5 x 7 x 23

Prime factors of 481 are 13 x 37

Prime factors of 978 are 2 x 3 x 163

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

Given numbers are 660, 805, 481, 978

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

Apply this formula for all numbers.

Step1:

LCM(660, 805) = 106260

GCD(660, 805) = ( 660 x 805 ) / 106260

= 660 / 805

= 660

Step2:

LCM(5, 481) = 2405

GCD(5, 481) = ( 5 x 481 ) / 2405

= 5 / 481

= 5

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 660, 805, 481, 978 is 1
