Given numbers are 155, 546, 280, 175

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 175 are 5 x 5 x 7

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

Given numbers are 155, 546, 280, 175

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

Apply this formula for all numbers.

Step1:

LCM(155, 546) = 84630

GCD(155, 546) = ( 155 x 546 ) / 84630

= 155 / 546

= 155

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

So, Greatest Common Divisor of 155, 546, 280, 175 is 1
