Given numbers are 140, 830, 747, 791

The list of prime factors of all numbers are

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

Prime factors of 830 are 2 x 5 x 83

Prime factors of 747 are 3 x 3 x 83

Prime factors of 791 are 7 x 113

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

Given numbers are 140, 830, 747, 791

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

Apply this formula for all numbers.

Step1:

LCM(140, 830) = 11620

GCD(140, 830) = ( 140 x 830 ) / 11620

= 140 / 830

= 140

Step2:

LCM(10, 747) = 7470

GCD(10, 747) = ( 10 x 747 ) / 7470

= 10 / 747

= 10

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 140, 830, 747, 791 is 1
