Given numbers are 441, 440, 615, 978

The list of prime factors of all numbers are

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 615 are 3 x 5 x 41

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 441, 440, 615, 978

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

Apply this formula for all numbers.

Step1:

LCM(441, 440) = 194040

GCD(441, 440) = ( 441 x 440 ) / 194040

= 441 / 440

= 441

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 441, 440, 615, 978 is 1
