Given numbers are 861, 743, 680, 670

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 743 are 743

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 670 are 2 x 5 x 67

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

Given numbers are 861, 743, 680, 670

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

Apply this formula for all numbers.

Step1:

LCM(861, 743) = 639723

GCD(861, 743) = ( 861 x 743 ) / 639723

= 861 / 743

= 861

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 861, 743, 680, 670 is 1
