Given numbers are 744, 920, 685, 842

The list of prime factors of all numbers are

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 685 are 5 x 137

Prime factors of 842 are 2 x 421

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

Given numbers are 744, 920, 685, 842

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

Apply this formula for all numbers.

Step1:

LCM(744, 920) = 85560

GCD(744, 920) = ( 744 x 920 ) / 85560

= 744 / 920

= 744

Step2:

LCM(8, 685) = 5480

GCD(8, 685) = ( 8 x 685 ) / 5480

= 8 / 685

= 8

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 744, 920, 685, 842 is 1
