Given numbers are 660, 668, 812, 749

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 668 are 2 x 2 x 167

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 749 are 7 x 107

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

Given numbers are 660, 668, 812, 749

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

Apply this formula for all numbers.

Step1:

LCM(660, 668) = 110220

GCD(660, 668) = ( 660 x 668 ) / 110220

= 660 / 668

= 660

Step2:

LCM(4, 812) = 812

GCD(4, 812) = ( 4 x 812 ) / 812

= 4 / 812

= 4

Step3:

LCM(4, 749) = 2996

GCD(4, 749) = ( 4 x 749 ) / 2996

= 4 / 749

= 4

So, Greatest Common Divisor of 660, 668, 812, 749 is 1
