GCD of numbers is the greatest common divisor

So, the GCD (101, 630, 780, 203) = 1.

Given numbers are 101, 630, 780, 203

The list of prime factors of all numbers are

Prime factors of 101 are 101

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Prime factors of 203 are 7 x 29

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

Given numbers are 101, 630, 780, 203

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

Apply this formula for all numbers.

Step1:

LCM(101, 630) = 63630

GCD(101, 630) = ( 101 x 630 ) / 63630

= 101 / 630

= 101

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 101, 630, 780, 203 is 1
