Given numbers are 165, 420, 534, 761

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 534 are 2 x 3 x 89

Prime factors of 761 are 761

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

Given numbers are 165, 420, 534, 761

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

Apply this formula for all numbers.

Step1:

LCM(165, 420) = 4620

GCD(165, 420) = ( 165 x 420 ) / 4620

= 165 / 420

= 165

Step2:

LCM(15, 534) = 2670

GCD(15, 534) = ( 15 x 534 ) / 2670

= 15 / 534

= 15

Step3:

LCM(3, 761) = 2283

GCD(3, 761) = ( 3 x 761 ) / 2283

= 3 / 761

= 3

So, Greatest Common Divisor of 165, 420, 534, 761 is 1
