Given numbers are 711, 861, 155, 124

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

Prime factors of 861 are 3 x 7 x 41

Prime factors of 155 are 5 x 31

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 711, 861, 155, 124

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

Apply this formula for all numbers.

Step1:

LCM(711, 861) = 204057

GCD(711, 861) = ( 711 x 861 ) / 204057

= 711 / 861

= 711

Step2:

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

= 3 / 155

= 3

Step3:

LCM(1, 124) = 124

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

= 1 / 124

= 1

So, Greatest Common Divisor of 711, 861, 155, 124 is 1
