Given numbers are 105, 840, 220, 254

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 254 are 2 x 127

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

Given numbers are 105, 840, 220, 254

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

Apply this formula for all numbers.

Step1:

LCM(105, 840) = 840

GCD(105, 840) = ( 105 x 840 ) / 840

= 105 / 840

= 105

Step2:

LCM(105, 220) = 4620

GCD(105, 220) = ( 105 x 220 ) / 4620

= 105 / 220

= 105

Step3:

LCM(5, 254) = 1270

GCD(5, 254) = ( 5 x 254 ) / 1270

= 5 / 254

= 5

So, Greatest Common Divisor of 105, 840, 220, 254 is 1
