Given numbers are 821, 312, 744, 136

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Prime factors of 136 are 2 x 2 x 2 x 17

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

Given numbers are 821, 312, 744, 136

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

Apply this formula for all numbers.

Step1:

LCM(821, 312) = 256152

GCD(821, 312) = ( 821 x 312 ) / 256152

= 821 / 312

= 821

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

So, Greatest Common Divisor of 821, 312, 744, 136 is 1
