Given numbers are 478, 780, 201, 216

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

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

Prime factors of 201 are 3 x 67

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 478, 780, 201, 216

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

Apply this formula for all numbers.

Step1:

LCM(478, 780) = 186420

GCD(478, 780) = ( 478 x 780 ) / 186420

= 478 / 780

= 478

Step2:

LCM(2, 201) = 402

GCD(2, 201) = ( 2 x 201 ) / 402

= 2 / 201

= 2

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 478, 780, 201, 216 is 1
