Given numbers are 247, 772, 540, 653

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 772 are 2 x 2 x 193

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 653 are 653

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

Given numbers are 247, 772, 540, 653

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

Apply this formula for all numbers.

Step1:

LCM(247, 772) = 190684

GCD(247, 772) = ( 247 x 772 ) / 190684

= 247 / 772

= 247

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 247, 772, 540, 653 is 1
