Given numbers are 642, 544, 775, 716

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 775 are 5 x 5 x 31

Prime factors of 716 are 2 x 2 x 179

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

Given numbers are 642, 544, 775, 716

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

Apply this formula for all numbers.

Step1:

LCM(642, 544) = 174624

GCD(642, 544) = ( 642 x 544 ) / 174624

= 642 / 544

= 642

Step2:

LCM(2, 775) = 1550

GCD(2, 775) = ( 2 x 775 ) / 1550

= 2 / 775

= 2

Step3:

LCM(1, 716) = 716

GCD(1, 716) = ( 1 x 716 ) / 716

= 1 / 716

= 1

So, Greatest Common Divisor of 642, 544, 775, 716 is 1
