Given numbers are 606, 505, 780, 218

The list of prime factors of all numbers are

Prime factors of 606 are 2 x 3 x 101

Prime factors of 505 are 5 x 101

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

Prime factors of 218 are 2 x 109

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

Given numbers are 606, 505, 780, 218

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

Apply this formula for all numbers.

Step1:

LCM(606, 505) = 3030

GCD(606, 505) = ( 606 x 505 ) / 3030

= 606 / 505

= 606

Step2:

LCM(101, 780) = 78780

GCD(101, 780) = ( 101 x 780 ) / 78780

= 101 / 780

= 101

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 606, 505, 780, 218 is 1
