Given numbers are 429, 263, 542, 780

The list of prime factors of all numbers are

Prime factors of 429 are 3 x 11 x 13

Prime factors of 263 are 263

Prime factors of 542 are 2 x 271

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

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

Given numbers are 429, 263, 542, 780

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

Apply this formula for all numbers.

Step1:

LCM(429, 263) = 112827

GCD(429, 263) = ( 429 x 263 ) / 112827

= 429 / 263

= 429

Step2:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 429, 263, 542, 780 is 1
