Given numbers are 703, 687, 709, 840

The list of prime factors of all numbers are

Prime factors of 703 are 19 x 37

Prime factors of 687 are 3 x 229

Prime factors of 709 are 709

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 703, 687, 709, 840

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

Apply this formula for all numbers.

Step1:

LCM(703, 687) = 482961

GCD(703, 687) = ( 703 x 687 ) / 482961

= 703 / 687

= 703

Step2:

LCM(1, 709) = 709

GCD(1, 709) = ( 1 x 709 ) / 709

= 1 / 709

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 703, 687, 709, 840 is 1
