Given numbers are 657, 827, 420, 705

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 827 are 827

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

Prime factors of 705 are 3 x 5 x 47

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

Given numbers are 657, 827, 420, 705

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

Apply this formula for all numbers.

Step1:

LCM(657, 827) = 543339

GCD(657, 827) = ( 657 x 827 ) / 543339

= 657 / 827

= 657

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 705) = 705

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

= 1 / 705

= 1

So, Greatest Common Divisor of 657, 827, 420, 705 is 1
