Given numbers are 645, 196, 690, 262

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 262 are 2 x 131

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

Given numbers are 645, 196, 690, 262

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

Apply this formula for all numbers.

Step1:

LCM(645, 196) = 126420

GCD(645, 196) = ( 645 x 196 ) / 126420

= 645 / 196

= 645

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

So, Greatest Common Divisor of 645, 196, 690, 262 is 1
