Given numbers are 780, 434, 867, 619

The list of prime factors of all numbers are

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

Prime factors of 434 are 2 x 7 x 31

Prime factors of 867 are 3 x 17 x 17

Prime factors of 619 are 619

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

Given numbers are 780, 434, 867, 619

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

Apply this formula for all numbers.

Step1:

LCM(780, 434) = 169260

GCD(780, 434) = ( 780 x 434 ) / 169260

= 780 / 434

= 780

Step2:

LCM(2, 867) = 1734

GCD(2, 867) = ( 2 x 867 ) / 1734

= 2 / 867

= 2

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 780, 434, 867, 619 is 1
