Given numbers are 705, 672, 531, 217

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 531 are 3 x 3 x 59

Prime factors of 217 are 7 x 31

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

Given numbers are 705, 672, 531, 217

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

Apply this formula for all numbers.

Step1:

LCM(705, 672) = 157920

GCD(705, 672) = ( 705 x 672 ) / 157920

= 705 / 672

= 705

Step2:

LCM(3, 531) = 531

GCD(3, 531) = ( 3 x 531 ) / 531

= 3 / 531

= 3

Step3:

LCM(3, 217) = 651

GCD(3, 217) = ( 3 x 217 ) / 651

= 3 / 217

= 3

So, Greatest Common Divisor of 705, 672, 531, 217 is 1
