Given numbers are 212, 370, 100, 685

The list of prime factors of all numbers are

Prime factors of 212 are 2 x 2 x 53

Prime factors of 370 are 2 x 5 x 37

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 685 are 5 x 137

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

Given numbers are 212, 370, 100, 685

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

Apply this formula for all numbers.

Step1:

LCM(212, 370) = 39220

GCD(212, 370) = ( 212 x 370 ) / 39220

= 212 / 370

= 212

Step2:

LCM(2, 100) = 100

GCD(2, 100) = ( 2 x 100 ) / 100

= 2 / 100

= 2

Step3:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

So, Greatest Common Divisor of 212, 370, 100, 685 is 1
