Given numbers are 406, 172, 535, 660

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 172 are 2 x 2 x 43

Prime factors of 535 are 5 x 107

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 406, 172, 535, 660

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

Apply this formula for all numbers.

Step1:

LCM(406, 172) = 34916

GCD(406, 172) = ( 406 x 172 ) / 34916

= 406 / 172

= 406

Step2:

LCM(2, 535) = 1070

GCD(2, 535) = ( 2 x 535 ) / 1070

= 2 / 535

= 2

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 406, 172, 535, 660 is 1
