Given numbers are 155, 787, 306, 546

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 787 are 787

Prime factors of 306 are 2 x 3 x 3 x 17

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

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

Given numbers are 155, 787, 306, 546

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

Apply this formula for all numbers.

Step1:

LCM(155, 787) = 121985

GCD(155, 787) = ( 155 x 787 ) / 121985

= 155 / 787

= 155

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

Step3:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

So, Greatest Common Divisor of 155, 787, 306, 546 is 1
