Given numbers are 780, 188, 614, 139

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 188 are 2 x 2 x 47

Prime factors of 614 are 2 x 307

Prime factors of 139 are 139

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

Given numbers are 780, 188, 614, 139

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

Apply this formula for all numbers.

Step1:

LCM(780, 188) = 36660

GCD(780, 188) = ( 780 x 188 ) / 36660

= 780 / 188

= 780

Step2:

LCM(4, 614) = 1228

GCD(4, 614) = ( 4 x 614 ) / 1228

= 4 / 614

= 4

Step3:

LCM(2, 139) = 278

GCD(2, 139) = ( 2 x 139 ) / 278

= 2 / 139

= 2

So, Greatest Common Divisor of 780, 188, 614, 139 is 1
