Given numbers are 661, 652, 542, 660

The list of prime factors of all numbers are

Prime factors of 661 are 661

Prime factors of 652 are 2 x 2 x 163

Prime factors of 542 are 2 x 271

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 661, 652, 542, 660

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

Apply this formula for all numbers.

Step1:

LCM(661, 652) = 430972

GCD(661, 652) = ( 661 x 652 ) / 430972

= 661 / 652

= 661

Step2:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 661, 652, 542, 660 is 1
