Given numbers are 505, 619, 540, 280

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 619 are 619

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

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 505, 619, 540, 280

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

Apply this formula for all numbers.

Step1:

LCM(505, 619) = 312595

GCD(505, 619) = ( 505 x 619 ) / 312595

= 505 / 619

= 505

Step2:

LCM(1, 540) = 540

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

= 1 / 540

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 505, 619, 540, 280 is 1
