Given numbers are 628, 780, 365, 218

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

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

Prime factors of 365 are 5 x 73

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 628, 780, 365, 218

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

Apply this formula for all numbers.

Step1:

LCM(628, 780) = 122460

GCD(628, 780) = ( 628 x 780 ) / 122460

= 628 / 780

= 628

Step2:

LCM(4, 365) = 1460

GCD(4, 365) = ( 4 x 365 ) / 1460

= 4 / 365

= 4

Step3:

LCM(1, 218) = 218

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

= 1 / 218

= 1

So, Greatest Common Divisor of 628, 780, 365, 218 is 1
