Given numbers are 812, 740, 140, 689

The list of prime factors of all numbers are

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

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 689 are 13 x 53

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

Given numbers are 812, 740, 140, 689

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

Apply this formula for all numbers.

Step1:

LCM(812, 740) = 150220

GCD(812, 740) = ( 812 x 740 ) / 150220

= 812 / 740

= 812

Step2:

LCM(4, 140) = 140

GCD(4, 140) = ( 4 x 140 ) / 140

= 4 / 140

= 4

Step3:

LCM(4, 689) = 2756

GCD(4, 689) = ( 4 x 689 ) / 2756

= 4 / 689

= 4

So, Greatest Common Divisor of 812, 740, 140, 689 is 1
