Given numbers are 268, 780, 545, 486

The list of prime factors of all numbers are

Prime factors of 268 are 2 x 2 x 67

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 545 are 5 x 109

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 268, 780, 545, 486

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

Apply this formula for all numbers.

Step1:

LCM(268, 780) = 52260

GCD(268, 780) = ( 268 x 780 ) / 52260

= 268 / 780

= 268

Step2:

LCM(4, 545) = 2180

GCD(4, 545) = ( 4 x 545 ) / 2180

= 4 / 545

= 4

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 268, 780, 545, 486 is 1
