Given numbers are 660, 841, 781, 444

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 841 are 29 x 29

Prime factors of 781 are 11 x 71

Prime factors of 444 are 2 x 2 x 3 x 37

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

Given numbers are 660, 841, 781, 444

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

Apply this formula for all numbers.

Step1:

LCM(660, 841) = 555060

GCD(660, 841) = ( 660 x 841 ) / 555060

= 660 / 841

= 660

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 660, 841, 781, 444 is 1
