Given numbers are 720, 292, 685, 100

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 292 are 2 x 2 x 73

Prime factors of 685 are 5 x 137

Prime factors of 100 are 2 x 2 x 5 x 5

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

Given numbers are 720, 292, 685, 100

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

Apply this formula for all numbers.

Step1:

LCM(720, 292) = 52560

GCD(720, 292) = ( 720 x 292 ) / 52560

= 720 / 292

= 720

Step2:

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

= 4 / 685

= 4

Step3:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

So, Greatest Common Divisor of 720, 292, 685, 100 is 1
