Given numbers are 298, 543, 830, 780

The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 543 are 3 x 181

Prime factors of 830 are 2 x 5 x 83

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 298, 543, 830, 780

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

Apply this formula for all numbers.

Step1:

LCM(298, 543) = 161814

GCD(298, 543) = ( 298 x 543 ) / 161814

= 298 / 543

= 298

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 298, 543, 830, 780 is 1
