Given numbers are 455, 786, 508, 124

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 786 are 2 x 3 x 131

Prime factors of 508 are 2 x 2 x 127

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 455, 786, 508, 124

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

Apply this formula for all numbers.

Step1:

LCM(455, 786) = 357630

GCD(455, 786) = ( 455 x 786 ) / 357630

= 455 / 786

= 455

Step2:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 455, 786, 508, 124 is 1
