Given numbers are 136, 340, 920, 921

The list of prime factors of all numbers are

Prime factors of 136 are 2 x 2 x 2 x 17

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

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 921 are 3 x 307

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

Given numbers are 136, 340, 920, 921

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

Apply this formula for all numbers.

Step1:

LCM(136, 340) = 680

GCD(136, 340) = ( 136 x 340 ) / 680

= 136 / 340

= 136

Step2:

LCM(68, 920) = 15640

GCD(68, 920) = ( 68 x 920 ) / 15640

= 68 / 920

= 68

Step3:

LCM(4, 921) = 3684

GCD(4, 921) = ( 4 x 921 ) / 3684

= 4 / 921

= 4

So, Greatest Common Divisor of 136, 340, 920, 921 is 1
