Given numbers are 780, 100, 658, 819

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 100 are 2 x 2 x 5 x 5

Prime factors of 658 are 2 x 7 x 47

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 780, 100, 658, 819

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

Apply this formula for all numbers.

Step1:

LCM(780, 100) = 3900

GCD(780, 100) = ( 780 x 100 ) / 3900

= 780 / 100

= 780

Step2:

LCM(20, 658) = 6580

GCD(20, 658) = ( 20 x 658 ) / 6580

= 20 / 658

= 20

Step3:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

So, Greatest Common Divisor of 780, 100, 658, 819 is 1
