Given numbers are 155, 615, 546, 221

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 221 are 13 x 17

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

Given numbers are 155, 615, 546, 221

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

Apply this formula for all numbers.

Step1:

LCM(155, 615) = 19065

GCD(155, 615) = ( 155 x 615 ) / 19065

= 155 / 615

= 155

Step2:

LCM(5, 546) = 2730

GCD(5, 546) = ( 5 x 546 ) / 2730

= 5 / 546

= 5

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 155, 615, 546, 221 is 1
