Given numbers are 158, 780, 273, 578

The list of prime factors of all numbers are

Prime factors of 158 are 2 x 79

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

Prime factors of 273 are 3 x 7 x 13

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 158, 780, 273, 578

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

Apply this formula for all numbers.

Step1:

LCM(158, 780) = 61620

GCD(158, 780) = ( 158 x 780 ) / 61620

= 158 / 780

= 158

Step2:

LCM(2, 273) = 546

GCD(2, 273) = ( 2 x 273 ) / 546

= 2 / 273

= 2

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 158, 780, 273, 578 is 1
