Given numbers are 217, 140, 492, 915

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 217, 140, 492, 915

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

Apply this formula for all numbers.

Step1:

LCM(217, 140) = 4340

GCD(217, 140) = ( 217 x 140 ) / 4340

= 217 / 140

= 217

Step2:

LCM(7, 492) = 3444

GCD(7, 492) = ( 7 x 492 ) / 3444

= 7 / 492

= 7

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 217, 140, 492, 915 is 1
