Given numbers are 780, 920, 577, 160

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 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 577 are 577

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 780, 920, 577, 160

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

Apply this formula for all numbers.

Step1:

LCM(780, 920) = 35880

GCD(780, 920) = ( 780 x 920 ) / 35880

= 780 / 920

= 780

Step2:

LCM(20, 577) = 11540

GCD(20, 577) = ( 20 x 577 ) / 11540

= 20 / 577

= 20

Step3:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

So, Greatest Common Divisor of 780, 920, 577, 160 is 1
