Given numbers are 340, 615, 357, 672

The list of prime factors of all numbers are

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 615 are 3 x 5 x 41

Prime factors of 357 are 3 x 7 x 17

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 340, 615, 357, 672

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

Apply this formula for all numbers.

Step1:

LCM(340, 615) = 41820

GCD(340, 615) = ( 340 x 615 ) / 41820

= 340 / 615

= 340

Step2:

LCM(5, 357) = 1785

GCD(5, 357) = ( 5 x 357 ) / 1785

= 5 / 357

= 5

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 340, 615, 357, 672 is 1
