Given numbers are 780, 342, 705, 610

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 342 are 2 x 3 x 3 x 19

Prime factors of 705 are 3 x 5 x 47

Prime factors of 610 are 2 x 5 x 61

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

Given numbers are 780, 342, 705, 610

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

Apply this formula for all numbers.

Step1:

LCM(780, 342) = 44460

GCD(780, 342) = ( 780 x 342 ) / 44460

= 780 / 342

= 780

Step2:

LCM(6, 705) = 1410

GCD(6, 705) = ( 6 x 705 ) / 1410

= 6 / 705

= 6

Step3:

LCM(3, 610) = 1830

GCD(3, 610) = ( 3 x 610 ) / 1830

= 3 / 610

= 3

So, Greatest Common Divisor of 780, 342, 705, 610 is 1
