Given numbers are 420, 849, 682, 157

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 849 are 3 x 283

Prime factors of 682 are 2 x 11 x 31

Prime factors of 157 are 157

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

Given numbers are 420, 849, 682, 157

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

Apply this formula for all numbers.

Step1:

LCM(420, 849) = 118860

GCD(420, 849) = ( 420 x 849 ) / 118860

= 420 / 849

= 420

Step2:

LCM(3, 682) = 2046

GCD(3, 682) = ( 3 x 682 ) / 2046

= 3 / 682

= 3

Step3:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

So, Greatest Common Divisor of 420, 849, 682, 157 is 1
