Given numbers are 124, 905, 624, 654

The list of prime factors of all numbers are

Prime factors of 124 are 2 x 2 x 31

Prime factors of 905 are 5 x 181

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 124, 905, 624, 654

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

Apply this formula for all numbers.

Step1:

LCM(124, 905) = 112220

GCD(124, 905) = ( 124 x 905 ) / 112220

= 124 / 905

= 124

Step2:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 124, 905, 624, 654 is 1
