Given numbers are 280, 770, 213, 662

The list of prime factors of all numbers are

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

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 213 are 3 x 71

Prime factors of 662 are 2 x 331

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

Given numbers are 280, 770, 213, 662

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

Apply this formula for all numbers.

Step1:

LCM(280, 770) = 3080

GCD(280, 770) = ( 280 x 770 ) / 3080

= 280 / 770

= 280

Step2:

LCM(70, 213) = 14910

GCD(70, 213) = ( 70 x 213 ) / 14910

= 70 / 213

= 70

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 280, 770, 213, 662 is 1
