Given numbers are 742, 520, 155, 633

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 155 are 5 x 31

Prime factors of 633 are 3 x 211

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

Given numbers are 742, 520, 155, 633

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

Apply this formula for all numbers.

Step1:

LCM(742, 520) = 192920

GCD(742, 520) = ( 742 x 520 ) / 192920

= 742 / 520

= 742

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

So, Greatest Common Divisor of 742, 520, 155, 633 is 1
