Given numbers are 801, 546, 640, 660

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

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

Given numbers are 801, 546, 640, 660

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

Apply this formula for all numbers.

Step1:

LCM(801, 546) = 145782

GCD(801, 546) = ( 801 x 546 ) / 145782

= 801 / 546

= 801

Step2:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 801, 546, 640, 660 is 1
