Given numbers are 654, 623, 705, 511

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 623 are 7 x 89

Prime factors of 705 are 3 x 5 x 47

Prime factors of 511 are 7 x 73

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

Given numbers are 654, 623, 705, 511

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

Apply this formula for all numbers.

Step1:

LCM(654, 623) = 407442

GCD(654, 623) = ( 654 x 623 ) / 407442

= 654 / 623

= 654

Step2:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 654, 623, 705, 511 is 1
