Given numbers are 780, 524, 117, 189

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 524 are 2 x 2 x 131

Prime factors of 117 are 3 x 3 x 13

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 780, 524, 117, 189

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

Apply this formula for all numbers.

Step1:

LCM(780, 524) = 102180

GCD(780, 524) = ( 780 x 524 ) / 102180

= 780 / 524

= 780

Step2:

LCM(4, 117) = 468

GCD(4, 117) = ( 4 x 117 ) / 468

= 4 / 117

= 4

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 780, 524, 117, 189 is 1
