Given numbers are 154, 780, 575, 105

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

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

Prime factors of 575 are 5 x 5 x 23

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 154, 780, 575, 105

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

Apply this formula for all numbers.

Step1:

LCM(154, 780) = 60060

GCD(154, 780) = ( 154 x 780 ) / 60060

= 154 / 780

= 154

Step2:

LCM(2, 575) = 1150

GCD(2, 575) = ( 2 x 575 ) / 1150

= 2 / 575

= 2

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 154, 780, 575, 105 is 1
