Given numbers are 203, 100, 780, 135

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 135 are 3 x 3 x 3 x 5

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

Given numbers are 203, 100, 780, 135

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

Apply this formula for all numbers.

Step1:

LCM(203, 100) = 20300

GCD(203, 100) = ( 203 x 100 ) / 20300

= 203 / 100

= 203

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

So, Greatest Common Divisor of 203, 100, 780, 135 is 1
