Given numbers are 217, 625, 920, 154

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 217, 625, 920, 154

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

Apply this formula for all numbers.

Step1:

LCM(217, 625) = 135625

GCD(217, 625) = ( 217 x 625 ) / 135625

= 217 / 625

= 217

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 217, 625, 920, 154 is 1
