Given numbers are 660, 765, 892, 445

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 765 are 3 x 3 x 5 x 17

Prime factors of 892 are 2 x 2 x 223

Prime factors of 445 are 5 x 89

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

Given numbers are 660, 765, 892, 445

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

Apply this formula for all numbers.

Step1:

LCM(660, 765) = 33660

GCD(660, 765) = ( 660 x 765 ) / 33660

= 660 / 765

= 660

Step2:

LCM(15, 892) = 13380

GCD(15, 892) = ( 15 x 892 ) / 13380

= 15 / 892

= 15

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 660, 765, 892, 445 is 1
