Given numbers are 345, 740, 987, 260

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 987 are 3 x 7 x 47

Prime factors of 260 are 2 x 2 x 5 x 13

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

Given numbers are 345, 740, 987, 260

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

Apply this formula for all numbers.

Step1:

LCM(345, 740) = 51060

GCD(345, 740) = ( 345 x 740 ) / 51060

= 345 / 740

= 345

Step2:

LCM(5, 987) = 4935

GCD(5, 987) = ( 5 x 987 ) / 4935

= 5 / 987

= 5

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 345, 740, 987, 260 is 1
